Question

Crystal earns $5.50 per hour mowing lawns. Write a rule to describe how the amount 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

5.50h=m
if you plug in 3.75 into "h" Crystal would make about $20.63

Answer 2

Answer:  Crystal would earn $20.625 by working 3 hours and 45 minutes.

Step-by-step explanation:

Since we have given that

Cost per hour for mowing lawns = $5.50

Let h be the number of hours.

Let the amount of money be 'm'.

So, the equation would be

$m=5.50h$

If number of hours = 3 hours 45 minutes = $3\dfrac{45}{60}=3\dfrac{3}{4}=\dfrac{15}{4}$

So, Amount of money earned by Crystal would be

$m=5.50\times \dfrac{15}{4}\\\\m=\ 20.625$

Hence, Crystal would earn $20.625 by working 3 hours and 45 minutes.
