Question 7 of 1893

Carpet stain protector costs $0.65 per square yard to apply.

How much will it cost to apply the protectant to a 16-foot ֳ— 18-foot carpet?

Answer

Suggested Answer

The suggested answer is C.

To determine the number of square yards to be protected, multiply 16 feet by 18 feet to determine the number of square feet, 288. Then divide 288 by 9 to convert square feet to square yards (1 square yard = 3 feet ֳ— 3 feet = 9 square feet). Multiply the quotient, 32 square yards, by the cost of protection per square yard,
$0.65, to get the correct answer, $20.80. Remember to perform all the steps in a calculation.
Question 8 of 1893

A printing plant that produces baseball cards has a monthly overhead of $6,000. It costs 18 cents to print each card, and the cards sell for 30 cents each.

How many cards must the printing plant sell each month in order to make a profit?

Answer

Suggested Answer

The suggested answer is C.

Let x = the number of cards printed and sold each month. Therefore, cost is equal to 6000 + 18x, and revenue is equal to 0.30x. You're looking for the point where revenue is greater than the cost (revenue > cost). The inequity is 0.30x > 6000 + 18x. Subtracting 18x from both sides of the inequity results in 0.12x > 6000.
Divide both sides by 0.12. The result is that x > 50,000. The printing plant would have to print and sell 50,000 cards per month to make a profit.
Question 9 of 1893

Joe received an hourly wage of $8.15. His boss gave him a 7% raise.

How much does Joe make per hour now?

Answer

Suggested Answer

The suggested answer is C.

To calculate the new wage, start off by multiplying $8.15 ֳ— 0.07 = $0.57. Then add that number (the amount of Joe's raise) to his original hourly wage. Joe's new hourly wage is $8.15 + $0.57 = $8.72.
