Question

A. $82.50

B. $72.75

C. $66.00

D. $41.25

Answer 1

Answer: A. $82.50

Explanation: First, calculate how much wall will be covered. Two sides of the room are 17 ft, and two are 16 ft. That’s a total of 66 ft of wall. (17 + 17 + 16 + 16 = 66.) Now, multiply by the cost of wallpaper. 66 * 1.25 = 82.5.
