You are trying to figure out how to spend your summer. You have two options for jobs. Babysitting (b) pays $12 an hour and cleaning houses (c) pays $15 an hour. You would like to make sure you make at least $420 per week.

c

Step-by-step explanation:

To get at least $420 with the babysitting job, you have to work 35 hours a week which if you work 5 days a week, you will have to work 7 hours a day, but if you were working 7 days a week, you would have to work for 5 hours a day.

To get at east $420 with the cleaning job, you have to work 28 hours a week. If you worked 5 days a week, you would have to work 5.6 hours a day, but if you worked 7 days a week, you would only have to work 4 hours a day.

Either way, the cleaning job pays more per hour, which means that you would have to work less hours to get the same amount of money that you would get for babysitting.

good bye
