Question

The bill from your plumber was $134. The cost for labor was $32 per hour. The cost for materials

was $46. How many hours did the plumber work.

Answer 1

2.75 hours, or 2 hours and 45 minutes

Explanation:

Subtract the cost of materials from the bill, 134-46=88.

Then, for every hour, he charges 32, so divide the difference by 32, 88/32.
