------------------------------------------------ You are trying to figure out how to spend your summer. You have two options for jobs: babysitting and cleaning houses.

- Babysitting (b) pays $12 an hour.
- Cleaning houses (c) pays $15 an hour.

You would like to make at least $420 per week.

1. If you work 32 hours cleaning, how many hours do you need to work babysitting to earn $420 for the week?

2. If you work 10 hours babysitting, how many hours do you need to work cleaning houses to reach your goal of $420?

Answer :

Answer: 0 hours babysitting, 20 hours cleaning

Step-by-step explanation:

Babysitting equation: 12b

Cleaning houses equation: 15c

What you would like to make: (b or c) = at least 420

15(32) = $480, so you would not need to babysit that week since it is more than $420.

12(10) = 120

15c + 120 = 420

15c = 300

c = 20 hours of cleaning to reach your goal.
