Question

Aldo wants to earn more than $87 trimming trees. He charges $8 per hour and pays $9 in equipment fees. What are the possible numbers of hours Aldo could trim trees? Use "t" for the number of hours.

Answer 1

Aldo needs to work more than 12 hours trimming trees to earn more than $87, after considering the equipment fees.

Step-by-step explanation:

Aldo wants to earn more than $87 trimming trees. To determine the number of hours t that Aldo needs to work to meet this goal, we must set up an inequality that represents his earnings. Aldo charges $8 per hour, and pays $9 in equipment fees. The inequality to represent this situation is:

8t - 9 > 87

Now we solve for t:

1. Add 9 to both sides of the inequality:
2. 8t > 96
3. Divide both sides by 8:
4. t > 12

The possible number of hours Aldo could work to earn more than $87 is any number greater than 12 hours.
