Answer:
$6.70 per hour
Step-by-step explanation:
We want to compare the pay for 1 hour's work.
<h3>Melanie's pay</h3>
The equation tells us that her pay for working 1 hour can be found from the equation using x=1.
y = 22.2x
y = 22.2×1 = 22.2 . . . . pay for 1 hour
Melanie earns $22.20 per hour.
<h3>Olivia's pay</h3>
We assume that Olivia's pay is proportional to hours worked, so pay for 40 hours will be 40 times 1 hour's pay.
pay per hour = $1156/(40 h) = $28.90/h
Olivia earns $28.90 per hour.
<h3>Pay difference</h3>
The difference in their rates of pay is ...
$28.90 -22.20 = $6.70
Melanie earns $6.70 less per hour than Olivia.
