Question

Joe wants to earn at least $73 trimming trees. He charges $7 an hour and pays $4 in equtment fees. What are the possible number of hours that joe could trim trees?

Use t for the number of hours.
Write your answer as an inequality solved for t

Answer 1

The number of hours to earn at least $73.
7t - 4 ≤ 73
Where t is the number of hours.
Now,
7t - 4 ≤ 73
7t ≤ 73 + 4
7t ≤ 77
t ≤ 11
Thus,
The number of hours is 11.
