Question

The bill from your plumber was 134. The cost of labor was 32 per hour. The cost of materials was 46. How many hours did the plumber worked

Answer 1

2.75 hours.

The equation would be 32x + 46 = 134. So we subtract 46 from 134 and get 88. Now we have to divide that by 32 to get the total of 2.75 hours
