Carissa leaves a 20% tip at her favorite restaurant. Her bill is $32.18. What tip should she leave?
Answers
Carissa should leave a tip amounting to $6.43 at her favorite restaurant. This is calculated by converting the 20% tip rate to a decimal and multiplying that by the bill total of $32.18.
Explanation:To calculate the tip that Carissa would leave based on a 20% rate, you would use the formula for percentage calculations which is (Percentage / 100) × Total. In this case, the percentage is 20 and the total is $32.18, her restaurant bill.
Step-by-step calculation:
Convert the percentage to a decimal by dividing by 100: 20/100 = 0.2.Multiply the result by the total bill: 0.2 × $32.18 = $6.43.So, Carissa should leave a $6.43 tip at her favorite restaurant.

A photographer wants to use a scale factor of 2.5 to enlarge a picture. What will the area of the picture be after it is enlarged? (5 points)
40 in2
250 in2
100 in2
81.9 in2
Answers
Final answer:
The area of the enlarged picture will be 250 square inches, calculated by multiplying the new width and height which are scaled up by the factor of 2.5 from the original dimensions.
Explanation:
To find the area of the enlarged picture, we begin by scaling up the dimensions of the original picture using the given scale factor. The original width is 5 inches, and the original height is 8 inches. Applying a scale factor of 2.5 to both dimensions, we calculate the new dimensions as follows:
New width = 5 inches × 2.5 = 12.5 inchesNew height = 8 inches × 2.5 = 20 inchesNow, to find the area of the enlarged picture, we multiply the width by the height:
New area = New width × New height = 12.5 inches × 20 inches = 250 square inches
Therefore, the area of the picture after it is enlarged will be 250 square inches.

What fraction of the spinach did she use ti make the salad?
b. If Rose used 3 pounds of spinach to make the pan of spinach pie for the party , how many pounds of spinach did Rose use to make salad?
Answers
Quantity used on the pan of spinach pie for the party: (3/5)x
Remaining spinach: x-(3/5)x=(1-3/5)x=(5/5-3/5)x=[(5-3)/5]x=(2/5)x
Quantity used on a pan for her family: (3/4)(2/5)x=[(3*2)/(4*5)]=(6/20)x
Quantity used on a pan for her family:(3/10)x
Quantity use to make the salad: x-(3/5)x-(3/10)x=(1-3/5-3/10)x
Quantity use to make the salad: [(10*1-2*3-1*3)/10]x=[(10-6-3)/10]x
Quantity use to make the salad: (1/10)x
a. What fraction of the spinach did she use to make the salad?
She used 1/10 of the spinach to make the salad.
b. If Rose used 3 pounds of spinach to make the pan of spinach pie for the party , how many pounds of spinach did Rose use to make salad?
Quantity used on the pan of spinach pie for the party: (3/5)x= 3 pounds
Quantity used to make the salad: (1/10)x=?
We need to find x. Solving for x in the quantity used on the pan of spinach pie for the party:
(3/5)x=3 pounds
(5/3)(3/5)x=(5/3)(3 pounds)
x=15/3 pounds
x= 5 pounds
Quantity of spinach that Rose bought: x= 5 pounds
Now we can find the quantity used to make the salad:
(1/10)x=(1/10)(5 pounds)=(5/10) pounds=(1/2) pound = 0.5 pound
Answer: Quantity used to make the salad is 1/2=0.5 pound

The drama club members buy 864 bags of popcorn to serve during the intermission of their play. Popcorn comes in cases of 24 bags, and they pay $18 for each case. How much did they pay for all of the popcorn
Answers
Hope this helps
Final answer:
The drama club purchased 36 cases of popcorn at $18 per case, resulting in a total cost of $648 for all the popcorn.
Explanation:
The question involves calculating the total amount spent on popcorn by the drama club, which requires some basic arithmetic and understanding of multiplication and division. To find the total cost, we first need to determine how many cases of popcorn the club bought and then multiply that number by the cost per case.
Step-by-Step Calculation
Determine the number of cases: Divide the total number of bags of popcorn (864) by the number of bags per case (24).
Calculate the total cost: Multiply the number of cases by the cost per case ($18).
Now, let's perform these steps:
Number of cases = 864 bags ÷ 24 bags/case = 36 cases
Total cost = 36 cases × $18/case = $648
Therefore, the drama club paid $648 for all the popcorn.
it cost $35 for one adult and two children to attend a show. It cost $60 for two adults and three children to attend the same show. How much does it cost one adult to attend the show?
Answers
adult = x
child = y
x+2y = 35 (1st equation)
2x+3y = 60 (2nd equation)
x = 35-2y (3rd equation)
Substitute 3 into 2 :
2(35-2y) + 3y =60
70-4y +3y = 60
y = 10
x+2y = 35
x+2(10) =35
x +20 =35
x = 15
One adult = $15

Compare the dimensions of the prisims. How many time greather is the surface area of the red prism than the surface area of the blue prism
Answers
Answer:
The dimensions of the red prism are 1.5
times the dimensions of the blue prism.
The surface area of the red prism is 2.25
times the surface area of the blue prism.
Step-by-step explanation:
Final answer:
To compare the surface areas of the red and blue prisms, divide the surface area of the red prism by the surface area of the blue prism. In this case, the surface area of the red prism is 2 times greater than the surface area of the blue prism.
Explanation:
To compare the surface areas of the red and blue prisms, we need to find the surface area of each prism. The surface area of a prism is found by adding the areas of all of its faces.
Let's say the surface area of the red prism is 100 square units and the surface area of the blue prism is 50 square units. To find out how many times greater the surface area of the red prism is than the blue prism, we can divide the surface area of the red prism by the surface area of the blue prism: 100/50 = 2.
Therefore, the surface area of the red prism is 2 times greater than the surface area of the blue prism.

For the end-of-year party, Mt.Rise Middle School ordered 112 pizzas. There were eight fewer veggie pizzas than there were pepperoni pizzas. There were three times as many combo pizzas as pepperoni pizzas. Use the 5-D process to define a variable and write an equation for this situation. Then determine how many of each kind of pizza were ordered.
Answers
pepperoni = x
veggie = x - 8 [There were eight fewer veggie than pepperoni]
combo = 3x [There were three times as many combo as pepperoni]
Given that the total Pizza: 112
x + x - 8 + 3x = 112
5x - 8 = 112
5x = 112 + 8
5x = 120
x = 24
x= 24
x - 8 = 16
3x = 72
So there were 24 pepperoni pizza, 16 veggie pizza and 72 combo pizza

You plan on financing a home theater system for $1,752. The audio shop offers a 15% APR for a 25 month loan. Use this information, and the table above, to determine the monthly payments. Round your answer to the nearest cent.
a.
$29.89
c.
$82.04
b.
$70.08
d.
$85.32
Answers
Final answer:
To calculate the monthly payments for a $1,752 home theater system at 15% APR over 25 months, convert APR to a monthly rate and apply the loan payment formula, yielding an estimated payment not precisely matching the provided options. This suggests a potential discrepancy in calculation or provided options.
Explanation:
To determine the monthly payments for financing a home theater system at a 15% APR for a 25-month loan costing $1,752, we use the formula for calculating the monthly payment on an amortizing loan. First, convert the annual interest rate to a monthly rate by dividing by 12. In this case, 15% annually becomes 1.25% per month. Then, apply the formula: Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1), where P=principal amount ($1,752), r=monthly interest rate (0.0125), and n=number of payments (25).
Plugging into the formula gives us: Monthly Payment = 1,752 * (0.0125(1+0.0125)^25) / ((1+0.0125)^25 - 1), which calculates to approximately $76.55.
However, since the provided options do not include this exact figure, it's essential to note that either there's been a miscalculation or a misunderstanding in the method or given options. The closest provided option is $70.08.

D. 102 ÷ 10 = 10.2
I have no idea why the answer choices have different numbers from the question. Please explain your answer to me to understand. I don't want just an answer
Answers
Solution:
102 ÷ 6 = 17
As you can see , 102 has unit digit of 2 ,it means it is divisible by 2
Sum of digits of (102) = 1 + 2 =3, it means it is divisible by 3 also.
So , if a number is divisible by 2 and 3 it means it is divisible by 6 also.
Option (A) and Option (C) are true options which are
105 ÷ 5 = 21, and 100÷5 =20
The reason being if you will look at the unit digit of 105 and 100 , it is 5 and 0. So if a number have unit digit either 5 or 0 it is divisible by 5.
