Question

Eric wants to earn at least 47$ trimming trees. He charges 6$ per hour and pays 7$ in equipment fees. What are the possible numbers of hours Eric could trim trees?

t=time

Answer 1

He wants to earn at least $47 but he also have to pay $7 for his equipment fees.

Therefore, he needs to earn at least $54.

Since he charges $6/h, t = 54 : 6 = 9.
