D. Harriet's Hair Styles

Answer 1

D. Harriet’s Hair Styles
You need to find the hourly rates of all of the jobs and compare them.
The work for Frank’s Furters is already done: $5.67 per hour.
For Harriet’s Hair Styles, you divide 80 by 15 to get 5.3, meaning the hourly rate is $5.30.
Babysitting has one extra step. First, you need to find out how many hours you work a month using ratios and then divide 250 by that number. In this case, it happened to be 40, and 250 divided by 49 is 6.25, so our hourly rate is $6.25.
Then, you just compare all of the values to find that the lowest hourly rate is Harriet’s Hair Styles at $5.30 per hour.
