Question

A plumber earns $50 for a repair job, plus an additional $75 per hour she works. On Tuesday, she completed 3 regular jobs and earned a total of more than $600.

 

Part A: Write an inequality that can be used to determine hh, 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. 

Answer 1

50+75h

for 3 jobs

150 +75h > 600

75h > 600-150 = 450

h > 450/75

h> 6 hours worked
