Question

Crystal earns $5.50 per hours mowing lawns. Write a rule to describe how the amout of money m earned is a function of the number of hours h spent mowing lawns. How much does crystal earn if she works 3 hours and 45 minutes?

Answer 1

She earns $5.50 for every hour so:

`m = 5.5h`
3 hours and 45 minutes is 3.75 hours.

`m = 5.5(3.75)`

`m = 20.625`
After rounding, she earns $20.63.
