Answer:
Comparing the two friends earning Montraie earns $ 0.5 per hour less than Serenity
Explanation:
The equation for the earning for Montraie is y = 19.2x
Using the equation in 38 hours Montraie will earn
y = 19.2 * 38
y = 729.6
This means that Montraie earns 19.2 per hour
For Serenity the earning per hour is solved
= 748.60 / 38
= 19.7
comparing both earnings
Serenity earning - Montaie earning
= 19.7 - 19.2
= 0.5
