A. $38.18 B. $45.12 C. $47.73 D. $59.27 

Definition
B. $45.12
Your first step is to determine the number of miles traveled. Multiply the rate of travel by the time. 48 × 7 = 336 miles. The amount of gas used is the total miles driven, divided by the number of miles per gallon. 336 ÷ 21 = 16 gallons of gasoline used. At the price of $2.82 per gallon, you spent $45.12 for gas ($2.82 × 16 = $45.12).

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?
A. 150 residents
B. 200 residents
C. 250 residents
D. 300 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.

A train headed south for Wichita left the station at the same time a train headed north for Des Moines left the same station. The train headed for Wichita traveled at 55 miles per hour.

Definition
D. 375 miles The train headed for Wichita traveled 55 miles per hour × 3 hours = 165 total miles. The train headed for Des Moines traveled 70 miles per hour × 3 hours = 210 total miles. Adding the distances together gives you the number of miles apart the two trains were after three hours: 210 + 165 = 375. Another option: You can add the two rates of speed (55 + 70) and multiply the sum by 3 hours (125 × 3 hours = 375).

First multiply length & width to determine the area of the patio: 12 feet × 14 feet = 168 square feet. Next determine the area in square inches that needs to be covered: 168 square feet × 12 inches = 2,016 square inches. Finally, divide that answer by the size of the stones to determine the number of stones needed: 2,016 ÷ 8 = 252.

A computer programmer is making $25,000 per year. 28% of her salary is withheld for federal and state deductions. How much is the computer programmer’s net pay?
A. $20,000
B. $7,000
C. $18,750
D. $18,000 

Definition
D. $18,000
Calculate the amount of the deduction by multiplying her salary by the percent deducted: $25,000 × 28% = $25,000 × 0.28 = $7,000. Subtract that product from the salary to determine the net pay: $25,000 − $7,000 = $18,000.

A cube has a volume of 64 cubic inches. What’s its surface area?
A. 16 square inches
B. 64 square inches
C. 96 square inches
D. 32 square inches 

Definition
C. 96 square inches
Volume is calculated by multiplying length times width times height (V = lwh). Because the edges are equal on a cube, each edge is 4 inches. The cube root of 64 produces this number: 64 = 4 × 4 × 4. The area of one side of the cube is 4 × 4 = 16, and because a cube has 6 sides, you multiply 16 × 6 to find the surface area of the cube, 96 inches. 


Term
A square box has a volume of 64 cubic inches. What’s its perimeter?
A. 8 inches
B. 16 inches
C. 64 inches
D. 32 inches

Volume equals length times width times height (V = lwh). In this case, V = 64, so one side of the box is 4–inches long. The cube root of 64 produces this number: 64 = 4 × 4 × 4. Find the perimeter by adding the four sides together: 4 + 4 + 4 + 4 = 16.

The formula to determine the mechanical advantage of an incline plane is Length of Ramp ÷ Height of Ramp = Weight of Object ÷ Effort.
8 ÷ 4 = 400 ÷ E
8⁄4 = 400⁄E
8E = 1,600
8E⁄8 = 1,600⁄8
E = 200

A. 10
B. 15
C. 20
D. 200
