A carpenter needs to cut four sections, each 3–feet 8–inches long, from a piece of molding. If the board is only sold by the foot, what’s the shortest length of board she can buy?
A. 15 feet
Convert the mixed number to inches. 3 feet 8 inches equals 44 inches (12 inches per foot × 3 feet = 36 inches + 8 inches = 44 inches). 44 inches (length each section needs to be) × 4 (number of sections needed) = 176 inches (total molding needed). To determine the amount of molding needed in feet, convert 176 inches into feet by dividing 176 inches by 12 inches. You get 1423feet, so the shortest board length is 15 feet.

Kiya had a coupon for 10% off one frozen turkey breast. The turkey breasts cost $8.50 each, and Kiya bought two. How much did she pay?
A. $16.15
One turkey breast costs $8.50 minus 10% of $8.50, or $8.50 − $0.85 = $7.65. The other turkey breast is full price. $7.65 + $8.50 = $16.15.
Stan bought a monster truck for $2,000 down and payments of $450 a month for five years. What’s the total cost of the monster truck?

B. $29,000
Five years contain 60 months, so multiply $450 (monthly payment) × 60 = $27,000 (total payments). Then add $27,000 (total payments) + $2,000 (down payment) = $29,000 (total cost).
Darla spent $120.37 on groceries in January, $108.45 in February, and $114.86 in March. What was the average monthly cost of Darla’s groceries?
D. $114.56
Add the three monthly amounts to determine the total amount Darla spent on groceries: $120.37 + $108.45 + $114.86 = $343.68. Divide the total by 3 to determine the average monthly cost: $114.56.
A waitress earns an average tip of 12% of the cost of the food she serves. If she serves $375 worth of food in one evening, how much money in tips will she earn on average?

B.$45 Multiply the total amount spent on food, $375, by 12% to determine the amount of tips. $375 × 0.12 = $45.
Carpet stain protector costs $0.65 per square yard to apply. How much will it cost to apply the protectant to a 16-foot by 18-foot carpet?
C. $20.80
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.

150 centimeters is equivalent to:
B. 12 meters
100 centimeters equal 1 meter, so 150 centimeters equal 1 12 meters.

Joe received an hourly wage of $8.15. His boss gave him a 7% raise. How much does Joe make per hour now?
C. $8.72
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.

As a member of FEMA, you’re required to set up a contingency plan to supply meals to residents of a town devastated by a tornado. A breakfast ration weighs 12 ounces and the lunch and dinner rations weigh 18 ounces each. Assuming a food truck can carry 3 tons and that each resident will receive 3 meals per day, how many residents can you feed from one truck during a 10–day period?
B. 200 residents
One ton = 2,000 pounds, so one truck can carry 6,000 pounds. There are 16 ounces in a pound, so one truck can carry 96,000 ounces. The total daily ration for each resident is 12 ounces + 18 ounces + 18 ounces, or 48 ounces. The number of daily rations supplied can be expressed as 96,000 ÷ 48 = 2,000. Dividing 2,000 by 10 days results in 200 residents who can be fed by one truck during this 10–day period.
