Question

A plumber earns $43 for a repair job, plus an additional $56 per hour he works. On Tuesday, he

completed 3 repair jobs and earned a total of more than $700.
Part A: Write an inequality that can be used to determine h, the number of hours the plumber
worked on Tuesday.

Answer 1

A. 150+75h>600

B. More than 6 hours

Explanation:

A plumber earns $50 for a repair job, so he will earn $150 for three repair jobs.

Let h be the number of hours the plumber worked on Tuesday. He earns $75 per hour worked, so he will earn $75h in h hours.

In total, the plumber earned $(150 + 75h)

A. On Tuesday, he completed 3 repair jobs and earned a total of more than $600. Thus

150+75h>600

B. Solve this inequality. Subtract 150:

150+75h-150>600-150

75h>450

Divide by 75:

h> 450/75

h>6

This means, the plumber worked more than 6 hours.
