Aplumber earns $50 for a repair job, plus an additional $75 per hour he works. on tuesday, he completed 3 repair jobs and earned a total of more than $600.
part a write an inequality that can be used to determine h, the number of hours the plumber worked tuesday
part b: solve your inequality to determine the number of hours the plumber worked tuesday. provide mathematical justification for your answer.

A.

B. More than 6 hours

Step-by-step 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

B. Solve this inequality. Subtract 150:

Divide by 75:

This means, the plumber worked more than 6 hours.

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
