Answer:
$8 each
Step-by-step explanation:
Cost of the gift= $90- $42= $48
Each friend pays: $48 divided by 6= $8
The total cost of the gift is $48, which is calculated by subtracting the change received ($42) from the amount paid ($90). Divided by six friends, each friend pays $8 for the gift.
Calculating Individual Payments for a Gift
To determine how much each friend pays for the gift, we first need to calculate the total cost of the gift. The friends together paid $90, and they received $42 in change. This means that the actual cost of the gift is the amount paid minus the change received:
Total cost of the gift = $90 - $42 = $48
Since six friends are sharing the cost equally, we divide the total cost by the number of friends to find out how much each person pays. To find the amount each friend pays:
Cost per friend = Total cost of the gift / Number of friends
Cost per friend = $48 / 6 = $8 per friend.
Therefore, each friend pays $8 for the gift.

There are 3 blobs per $1.50 what is 6 blobs per _____
Answer:
$3
Step-by-step explanation:
3 blobs for 1.50
that means 1 blob is (1.50 / 3) which is 50 cents per blob
0.50 * 6 = 3 dollars for 6 blobs
The question is about cost ratios. Given that 3 blobs are worth $1.50, a single blob is worth $0.50. Therefore, 6 blobs would cost $3.00.
Explanation:The question is asking about cost ratios. In the presented situation, there are 3 blobs for every $1.50. We can say that the cost of one blob is $1.50 divided by 3, which is $0.50. If we are looking for the cost of 6 blobs, we simply multiply the cost of one by 6, which gives us $3.00. Therefore, 6 blobs cost $3.00.

Sherry invested some money at 7% interest Sherry also invested $242 more than four times that amount at 6% how much is invested at each rate if Sherry receives $427.13 in interest after one year
$1331 is invested at 7% and $5566 is invested at 6%
Step-by-step explanation:
The formula of the simple interest is I = P r t, where
P is the money investedr is the rate of interest in decimalt is the time of investmentAssume that Sherry invested $P in the first account
∵ Sherry invested $P in the first account at 7% interest for 1 year
∵ I = P r t
∴ The interest of the 1st account = P( [tex]\frac{7}{100}[/tex] )(1)
∴ The interest of the 1st account = 0.07 P
∵ Sherry also invested $242 more than four times that amount at
6% for 1 year
- Multiply P by 4 and add 242 to the product
∴ Sherry invested in the 2nd account (4P + 242)
∵ I = P r t
∴ The interest of the 2nd account = (4P + 242)( [tex]\frac{6}{100}[/tex] )(1)
∴ The interest of the 2nd account = 0.06(4P + 242)
- Simplify it
∴ The interest of the 2nd account = 0.24 P + 14.52
∵ Sherry receives $427.13 in interest after one year
- Equate the 1st interest and the 2nd interest and equate the sum
by 427.13
∴ 0.07 P + 0.24 P + 14.52 = 427.13
∴ 0.31 P + 14.52 = 427.13
- Subtract 14.52 from both sides
∴ 0.31 P = 412.61
- Divide both sides by 0.31
∴ P = 1331
∵ She invested (4P + 242) in the 2nd account
- Substitute P by 1331
∴ She invested in the 2nd account = 4(1331) + 242 = 5566
∴ She invested $1331 at 7% interest
∴ She invested $5566 at 6% interest
$1331 is invested at 7% and $5566 is invested at 6%

given f(x)= -3/4x-6 and its domain: (-8, 0, 4) what is the range of the function?
The range of function is { 0, -6, -9}
Solution:Given that the function is:
[tex]f(x) = \frac{-3}{4}x - 6[/tex]
Also given its domain is (-8, 0, 4)
To find: Range of the function
Domain of the function is possible input of the function that is "x" and range of the function is possible output of the function that is f(x)
As there are only three input values for "x" that are (-8, 0, 4) we can determine the range by calculating value of f(x) for each of the x
For x = 8:
[tex]f(-8)=\frac{-3}{4} \times(-8)-6=6-6=0[/tex]
[tex]f(-8)=0[/tex]
For x = 0:
[tex]\begin{array}{l}{f(0)=\frac{-3}{4} \times(0)-6=-6} \\\\ {f(0)=-6}\end{array}[/tex]
For x = 4:
[tex]\begin{array}{l}{f(4)=\frac{-3}{4} \times(4)-6=-3-6=-9} \\\\ {f(4)=-9}\end{array}[/tex]
Thus the range of function is { 0, -6, -9}

A chemical company makes two brands of antifreeze. The first brand is 70% pure antifreeze, and the second brand is 85% pure antifreeze. In order to obtain 150 gallons of a mixture that contains 80% pure antifreeze, how many gallons of each brand of antifreeze must be used?
Answer:
50 gallos of 70%
100 gallons of 85%
Step-by-step explanation:
x = amount of 70% antifreeze
y = amount of 85% antifreeze
EQUATION 1: x + y = 150 (total of 150 gallons mixed)
EQUATION 2: .70x + .85y = .80(x + y)
Multiply second equation by 100 on both sides to remove the decimals 70x + 85y = 80(x + y)
70x + 85y = 80x + 80y (distributive)
70x - 80x + 85y - 80y = 0
-10x + 5y = 0
Now we have the following system of equations:
x + y = 150
-10x +5 y = 0
Multiply the first equation by 10 to get opposite coefficients for x; add the equations to eliminate x
10x + 10y = 1500
-10x + 5y = 0
------------------------------
15y = 1500
Solve for y 15y = 1500 y = 100
x+100=150 x=50
how many solutions are there to this equation 3(x-4)+5-x=2x-7

x =72.86. This means that 51 out of 70 is equivalent to 72.86%.
51/70 = x/100.
51 * 100 = 70 * x.
5100 = 70 x
5100 / 70 = x.
The result is x = 72.86.
So, x = 72.86.
This means 51 out of 70 is equivalent to 72.86 out of 100 as a percentage.
A movie theater sends out a coupon for 85% off the price of a ticket. Write an equation for the situation, where y is the price of the ticket with the coupon, and x is the original price of the ticket. Use pencil and paper. Draw a graph of the equation and explain why the line should only be in the first quadrant.
The equation is y=__________
(Use integers or decimals for any numbers in the expression).
Answer:
[tex]y=0.15x[/tex]
Step-by-step explanation:
Given:
Original price of the ticket is [tex]x[/tex]
Price after using the coupon is [tex]y[/tex]
Coupon discount is 85% of [tex]x=0.85x[/tex]
Therefore, the price after applying coupon is given as the difference of the original price and the coupon discount. That is,
[tex]y=x-0.85x=x(1-0.85)=0.15x\\\therefore y=0.15x[/tex]
The graph is shown below. The graph passes through the origin as the above relationship is a proportional relationship.
The line [tex]y=0.15x[/tex] strictly remains in the first quadrant as both [tex]x[/tex] and [tex]y[/tex] can't be negative as they represent price of tickets and price can never have negative values. Hence, only the first quadrant has both the values of [tex]x[/tex] and [tex]y[/tex] positive.
A yoga studio offers memberships that cost $60 per month for unlimited classes. The studio also accepts walk-ins, charging $10 per class. If someone attends enough classes in a month, the two options cost the same total amount. How many classes is that? What is that total amount?
Final answer:
To determine the number of classes at which the total cost for both options is the same, we can set up an equation. When attending 6 classes in a month, the total cost for both options will be the same, which is $60.
Explanation:
To determine the number of classes at which the total cost for both options is the same, we can set up an equation. Let x be the number of classes attended in a month.
For the membership option, the total cost is $60 per month.
For the walk-in option, the total cost is $10 multiplied by the number of classes attended.
Setting up the equation, we have:
60 = 10x
Dividing both sides by 10, we find:
x = 6 classes
So, when attending 6 classes in a month, the total cost for both options will be the same.
Using this value of x, we can find the total amount. For the membership option, it would be $60. For the walk-in option, the total amount is $10 multiplied by 6 classes, which is $60 as well.

Giselle pays $240 in advance on her account at the athletic club. Each time she uses the club, $5 is deducted from the account. Model the situation with a linear function.
A: b = 235 + 5x
B: b = 240 - 5x
C: b = 235 - 5x
D: b = 240 + 5x
Answer:
B) b = 240 - 5 x is the required expression to decipher the situation.
Step-by-step explanation:
The amount paid to the club in the advance = $240
Amount deducted in each visit = $5
Let us assume the number of times the club visited = x
So, the amount deducted in x visits = x ( $5) = 5x
Let b : amount Left after x visits
So, Amount left after x visits = Advance Amount - Deductions after x visits
⇒ b = $240 - 5x
or , b = 240 - 5x is the required expression to decipher the situation.
Answer:
Giselle pays $240 on advance
Each time she uses ,$5 is deducted
Let no of time she use be x
So, Amount deducted = 5x
As Giselle pays $240 in advance
So 5x amount will be deducted from $240 to get net amount
So b= 240-5x

The perimeter of one of the rectangular playrooms at Miss Pittypat's Day Care is 72 feet. It's width is 10 feet.
What is its area?
Answer:
The area of the rectangular playroom is 260 feet² .
Step-by-step explanation:
Given:
The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.
Now, to find its area we need the length .
So, putting the formula of perimeter we get it's length:
Let the length be l .
Perimeter = 2( length + width)
[tex]72=2(l+10)[/tex]
[tex]72=2l+20[/tex]
subtracting both sides from 20:
[tex]72-20=2l+20-20[/tex]
[tex]52=2l[/tex]
Dividing both sides by 2:
[tex]52\div2=2l\div2[/tex]
[tex]26=l[/tex]
Length is 26 feet.
And, to get the area we put the formula of finding the area:
[tex]Area=length\times width[/tex]
[tex]Area=26\times 10[/tex]
[tex]Area=260[/tex]
Therefore, the area of the rectangular playroom is 260 feet² .
Final answer:
To determine the area of the rectangular playroom at Miss Pittypat's Day Care, we calculate the length using the perimeter and width provided, then multiply the length by the width. The playroom's area is found to be 260 square feet.
Explanation:
The question involves calculating the area of a rectangle when given the perimeter and the width. To find the length, we first use the perimeter formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Since the perimeter is given as 72 feet and the width is 10 feet, we can solve for the length:
72 = 2l + 2(10)
72 = 2l + 20
52 = 2l
l = 26 feet
Once we have the length, we calculate the area by multiplying the length by the width:
Area = l × w
Area = 26 ft × 10 ft
Area = 260 square feet
Therefore, the area of the rectangular playroom is 260 square feet.

17 is added to a number, the result is 37 less than twice the number. Find the number
To find the number, subtract 37 from both sides of the equation and isolate 'x'. The number is 54.
Explanation:To find the number, let's represent it with the variable 'x'. The problem states that when 17 is added to the number, the result is 37 less than twice the number.
Mathematically, this can be represented as:
x + 17 = 2x - 37
To solve for 'x', we can start by subtracting 'x' from both sides of the equation:
17 = x - 37
Next, we can add 37 to both sides to isolate 'x':
54 = x
Therefore, the number is 54.
