Answer 2

Answer:

Step-by-step explanation:

This is a straight forward proportion.

9 hours = 35 dollars

1 hour = x                      

9:1::35:x                                                              Cross multiply

9 hour * x = 1 hour * 35 dollars.                        Divide by 9

9 hour / 9 hour x = 1 hour   35 dollars/9 hour

x = 35/9

x = $3.89 rounded.
