Erica babysits for 4.5 hours and is paid $27. If the people she babysits for have $34 to pay her, how long can they stay out?

Answer 1

Answer:

5 2/3 hours  

Step-by-step explanation:

We can use a ratio to solve this problem

hours over money

4.5 hours         x hours

-------------    =  ------------

27 dollars        34 dollars

Using cross products

4.5 * 34 = 27 * x

153 =27x

Divide each side by 27

153/27 = 27x/27

5.666666 hours
