Question

Aiden is working two summer jobs, making $20 per hour lifeguarding and making $6 per hour walking dogs. In a given week, he can work at most 13 total hours and must earn at least $120. If Aiden worked 4 hours walking dogs, determine the minimum number of whole hours lifeguarding that he must work to meet his requirements.

Answer 1

So, we know the total amount of money Aiden has to make is 120$, and he makes 6$ per hour walking dogs. Aiden worked his 4 hours walking dogs, and we know for each hour he walks dog’s he gets paid 6$. So multiply 6 and 4 (6x4), to get 24. We know the amount of money he has to get is 120, so divide 24 by 120 (120/24), to get your final answer 5.
