Answer:
a : [tex]m=5.50h[/tex]
b : $20.625
Step-by-step explanation:
Crystal earns $5.50 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.
[tex]m=5.50h[/tex]
when we will put the value of 'h' in the function, we will get the total money earned while working at the rate of $5.50 per hour.
b. How much does Crystal earn if she works 3 hours and 45 minutes?
45 minutes = [tex]\frac{45}{60}=0.75[/tex] hours.
So, total hours are [tex]3+0.75=3.75[/tex] hours
Hence, money earned in 3.75 hours = [tex]3.75\times5.50=20.625[/tex] dollars.
