| 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 142⁄3feet, 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. 1 1⁄2 meters
100 centimeters equal 1 meter, so 150 centimeters equal 1 1⁄2 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. | ||
