A house painter uses about 2 1/2 quarts of paint per hour on a specific type of wooden exterior trim. For an 8-hour day, the painter's preparation work is 3/4 of an hour, with 1/2 hour for cleanup. If the person paints the remainder of the 8 hours, compute the number of quarts of paint that will be used.

Question 2

Answer to Question 1

3/4 + 1/2 = 3/4 + 2/4 = 5/4 = 1 1/4 hours;
8 - 1 1/4 = 7 4/4 - 1 1/4 = 6 3/4 hours;
6 3/4 2 1/2 = 27/4 5/2 = 135/8 = 16 7/8 quarts

Answer to Question 2

2,225 0.07 190/360 = 82.20; 2,225 + 82.20 = 2,307.20
