Question

Crystal earns $5.25 per hour mowing lawns. a. Write a rule to describe how the amount of money m earned is a function of the number of hours h spent mowing lawns. b. How much does Crystal earn if she works 2 hours and 15 minutes

Answer 1

14.25 per hour mowing lawns

Answer 2

The rule would be m=5.25h

if she works 2 hours and 15 minutes( which is equal to 2.25 hours), you would plug that into the equation. 

m=5.25(2.25)

the final equation is 11.81=5.25(2.25) So Crystal earns $11.81
