does Montraie earn more money than serenity per hour or less? if so how much more or less
To compare Montraie's earnings per hour with Serenity's earnings, we need to first calculate Montraie's total earnings for x hours using the given equation y = 19.2x:
For Montraie:
Total earnings = 19.2 * x
Now, we need to find out how many hours Montraie worked to earn $748.60:
19.2 * x = 748.60
x = 748.60 / 19.2
x ≈ 39 hours
Montraie worked approximately 39 hours to earn $748.60.
Now, let's compare their earnings per hour:
Montraie's earnings per hour:
19.2
Serenity's earnings per hour:
748.60 / 38 ≈ 19.70
Therefore, Serenity earns more money per hour compared to Montraie. She earns $0.50 more per hour than Montraie.
