Question

Bob wants to earn more than $ 33 trimming trees. He charges $ 8 per hour and pays $ 7 in equipment fees. What are the possible numbers of hours Bob could trim trees? Use t for the number of hours. Write your answer as an inequality solved for t .

Answer 1

4 hours

Explanation:

Bon wants to earn more than $33.

He charges $8/hour

He pays $7 for equipment fee

Assume t = number of hours

7 + 8t ≥ 33

8t ≥ 33 - 7

8t ≥ 26

t ≥ 26 ÷ 8

t ≥ 3.25 hours

Possible possible number of hours = 4
