A person wants to change some cash for quarters to play arcade games. The player gives the cashier $25.00. How many quarters will the cashier give the player? (Enter numeric value only.)

Set up the proportion as fractions:

=

First, simplify the left side ratio:

= 30

This means for every 15 units on the left, there are 450 units. To maintain this proportion, the ratio on the right must behave similarly:

30 =

Now, solve for 𝑋X by cross-multiplying:

30⋅𝑋=225

Simplify to find X:

𝑋=​= 7.5

This correct calculation verifies that 𝑋=7.5, matching the proportion given.

Thus, the answer is A. X = 7.5.

To find the percentage overweight, first calculate the difference between his actual weight and his maximum desirable weight.

226 pounds – 204 pounds

= 22 pounds.

To find percentage overweight, divide this difference with the maximum desirable weight and then multiply by 100%.

% overweight = × 100%

= 10.78%

≈ 10%

From the given options, 10% is the closest option.

Therefore, the correct answer is

D. 10%

To find the cost of 15 books when 5 books cost $300, first determine the cost of one book by dividing the total cost by the number of books:

Costofonebook=$300 ÷ 5= $60

Next, calculate the cost for 15 books by multiplying the cost per book by the number of books:

Costfor15books=15×$60=$900

Therefore, 15 books will cost 900 dollars.

To find out how many fluid ounces are in 2gallons, first convert 2gallons to a single unit.

Since 1 gallon is equal to 128 fluid ounces, calculate the total number of ounces in 2 gallons as follows:

Convert 2gallons to an improper fraction:

2= gallons

Multiply by the number of ounces in one gallon:

× 128oz/gallon

=

=320oz

The correct answer is: D 320 oz
