Two friends, Montraie and Serenity, took summer jobs. The equation y = 19.2x represents Montraie's earnings in dollars and cents, y, for working x hours. Serenity earned $748.60 in 38 hours.

Question

does Montraie earn more money than serenity per hour or less? if so how much more or less

Answer 1

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.
