Question

Crystal earns $5.50 per hour mowing lawns. Write a rule to describe the amount of money m earned is a function of the number of hours h spent mowing lawns. How does Crystal earn if she works 3 hours 45 minutes? Round to the nearest cent.

Answer 1

Answer: Crystal earns $18.98 working 3 hours and 45 minutes.

Step-by-step explanation: Since m is the amount of money earned and we are trying to find how much money Crystal earned in h hours, the function will be set up as m = 5.50(h). If Crystal works 3.45 hours, we can plug this number into h: m = 5.50(3.45), which gives us $18.975. Rounded to the nearest cent, the answer would be $18.98 because 5 rounds 7 up.
