The lunch bill for Marty and Breanna add a dinner totaled $18.37. Tax on the meal was 6%, and they wanted to leave a 15% tip. How much was the meal including tax and tip?
Final answer:
To calculate the total cost of Marty and Breanna's meal including tax and tip, add a 6% tax and a 15% tip to the original bill of $18.37 to get a total of $22.23.
Explanation:
To find the total cost of the meal for Marty and Breanna including tax and tip, we first calculate the tax. Since the tax rate is 6%, we convert that to a decimal (0.06) and multiply by the total cost of the meal ($18.37):
0.06 × $18.37 = $1.10 (rounded to the nearest cent).
Next, we calculate the tip, which is 15% of the pre-tax meal cost. We turn 15% into a decimal (0.15) and multiply by the meal cost:
0.15 × $18.37 = $2.76 (rounded to the nearest cent).
To find the total amount paid including tax and tip, we add all the amounts together:
$18.37 + $1.10 + $2.76 = $22.23
So, the total cost of the meal including tax and tip is $22.23.

each week Samantha can pay as much $15 for her school at lunch. Write an inequality showing how much Samantha spends at lunch.
Let us say Samantha spends $x for her school at lunch every week.

The recipe makes enough stew for 6 people, and the ingredients cost $9.75. How much would it cost to serve 24 people? Use the rate table to solve the proportion.
Answer: The required cost of ingredients that would serve the recipe to 24 people is $39.
Step-by-step explanation: Given that a recipe makes enough stew for 6 people and the ingredients cost $9.75.
We are to find the cost of the ingredients that would make recipe to serve 24 people.
We are to use the rate table to solve the given problem.
Since the rate of increase of number of people is given by
[tex]\dfrac{24}{6}=4.[/tex]
Therefore, we will multiply the cost of ingredients for 6 people by 4.
Therefore, the cost of ingredient that makes the recipe to serve 24 people will be
[tex]=9.75\times 4\\\\=39.[/tex]
Thus, the required cost of ingredients that would serve the recipe to 24 people is $39.

Kersha has two jobs. During the day she works as an office clerk, and in the evening she works as a cashier. Her office job pays her $12.00 per hour. Her cashier job pays her $8.25 per hour. In one week, Kersha worked 55 hours. She earned a total of $585.
How many hours did Kersha work in each job?
Office clerk: 31 hours; cashier: 24 hours
Office clerk: 20 hours; cashier: 35 hours
Office clerk: 35 hours; cashier: 20 hours
Office clerk: 28 hours; cashier: 27 hours
The correct answer is that Kersha worked as an office clerk for 35 hours and as a cashier for 20 hours.
To solve this problem, we can set up a system of equations based on the information given. Let's denote the number of hours Kersha worked as an office clerk as [tex]\( x \)[/tex] and the number of hours she worked as a cashier as [tex]\( y \).[/tex]
From the problem statement, we know the following:
1. Kersha earns $12.00 per hour at her office job.
2. Kersha earns $8.25 per hour at her cashier job.
3. Kersha worked a total of 55 hours in one week.
4. Kersha earned a total of $585 in one week.
Using this information, we can write two equations:
For the total number of hours worked:
[tex]\[ x + y = 55 \][/tex] (Equation 1)
For the total earnings:
[tex]\[ 12x + 8.25y = 585 \][/tex] (Equation 2)
Now we have a system of two equations with two variables. We can solve this system using substitution or elimination. Let's use the substitution method.
First, we can solve Equation 1 for [tex]\( x \):[/tex]
[tex]\[ x = 55 - y \][/tex]
Now we substitute [tex]\( x \)[/tex] in Equation 2 with [tex]\( 55 - y \):[/tex]
[tex]\[ 12(55 - y) + 8.25y = 585 \][/tex]
Expanding the equation, we get:
[tex]\[ 660 - 12y + 8.25y = 585 \][/tex]
Combining like terms, we get:
[tex]\[ -3.75y = 585 - 660 \][/tex]
[tex]\[ -3.75y = -75 \][/tex]
Dividing both sides by -3.75 to solve for [tex]\( y \)[/tex], we get:
[tex]\[ y = \frac{-75}{-3.75} \][/tex]
[tex]\[ y = 20 \][/tex]
Now that we have the value of [tex]\( y \)[/tex], we can find [tex]\( x \)[/tex] using Equation 1:
[tex]\[ x = 55 - y \][/tex]
[tex]\[ x = 55 - 20 \][/tex]
[tex]\[ x = 35 \][/tex]
Therefore, Kersha worked 35 hours as an office clerk and 20 hours as a cashier. The correct option is:
Office clerk: 35 hours; cashier: 20 hours.

The other is 12 square yards. Which rug will fit Tucker's room? a length of 4 yards. One rug has an area of 16 square yards. The other is 12 square yards. Which rug will fit Tucker's room?
Answer:
Step-by-step explanation:we have 2 area rugs, and each has a length of 4 yards
Rug 1 has a area of 16 square yards, meaning that the width is also 4 yard(L*w=16, where Length=4)
Rug 2 has a Length of L=4 but the area is just 12 square yards, so here we have the width of 3 yards (12/4=3)
the rug number 2 will fit in tucker's bedroom

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Dwayne wants to buy a bowling ball that has a price of $120.
And, As a member of a bowling league, he is entitled to a 15% discount off the price of the bowling ball. He will also have to pay 6% sales tax on the discounted price of the bowling ball.
Now,
Here, Dwayne wants to buy a bowling ball that has a price of $120.
Hence, After 15% discount the price is,
⇒ 15% of 120
⇒ 15 x 120 / 100
⇒ $18
Hence, After discount the price is,
⇒ 120 - 18
⇒ $102
And, He will also have to pay 6% sales tax on the discounted price of the bowling ball.
Hence, The price of ball is,
⇒ $102 + 6% of 102
⇒ $102 + $6.12
⇒ $108.12
Since, Dwayne thinks that the final price of the bowling ball can be determined by taking 9% off the original price.
Hence, We can formulate;
⇒ $120 - 9% of 120
⇒ $120 - 10.8
⇒ $109.2
Thus, Dwayne is not correct.

D) 100 feet for $57.50
Answer:
Option C- 50 feet for $28.00 is the best deal because it offers rope $0.56 per feet.
Step-by-step explanation:
To know what is the best deal on rope, we calculate the price for 1 feet rope from the given deals.
A) 10 feet for $7.00
1 feet = 7.00 ÷ 10 = $0.70
B) 20 feet for $13.00
1 feet = 13.00 ÷ 20 = $0.65
C) 50 feet for $28.00
1 feet = 28 ÷ 50 = $0.56
D) 100 feet for $57.50
1 feet = 57.50 ÷ 100 = $0.575
Option C) 50 feet for $28.00 offers lowest price, so this is the best deal.
Answer:
The best deal is "50 feet for $28.00"
C is correct
Step-by-step explanation:
We need to buy tie down rope for moving furniture.
We have to choose best deal from four option.
We are given length of rope and price of rope.
We can identity best deal if we know the price of rope per feet.
So, first we change each option into per feet.
Option A) 10 feet for $7.00
Price of 10 feet rope = $7
Price of 1 feet rope = $0.70
Option B) 20 feet for $13.00
Price of 20 feet rope = $13.00
Price of 1 feet rope = $0.65
Option C) 50 feet for $28.00
Price of 50 feet rope = $28.00
Price of 1 feet rope = $0.56
Option D) 100 feet for $57.50
Price of 100 feet rope = $57.50
Price of 1 feet rope = $0.5750
Now, we arrange each per feet price and check best deal.
0.70 > 0.65 > 0.57 > 0.56
The minimum cost is $0.56
Hence, The best deal is "50 feet for $28.00"

So the rows are read from left to right, now down. This is probably a little late to be answering this, but see how the top row say 4 6 5? 4 quarters = 100, 6 dimes = 60, 5 nickels = 25, all together is 185. It's just asking you to fill in the blanks to make each row equal $1.87. So for pennies, you would put 2 to make 185+2 = 187 or $1.87. I was confused looking at this too.

What is the simplified form of the expression? 3/a-9b
Final answer:
The simplified form of 3/(a-9b) is 3/a - 1/3b.
Explanation:
The closest relevant excerpt appears to be “(a + b)/h, āb/h + (a + b)(a + b)/h = (a + b)/h” which simplifies to “(a + b)/h”, assuming the intention was to demonstrate simplification through common denominator aggregation or algebraic manipulation. The mostly likely possible simplification in this can be done in the following form.
The simplified form of the expression 3/(a-9b) is 3/a - 1/3b.
To simplify, we split the fraction into two: 3/a - 3/(3b) = 3/a - 1/3b.
