How much more does Myesha earn per hour than Wyatt?

1 answer

To find out how much more Myesha earns per hour than Wyatt, we can calculate the difference in their earnings per hour.

For Wyatt:
At 10 hours, Wyatt earns $163
At 20 hours, Wyatt earns $326

Wyatt's earnings per hour = (326-163)/(20-10) = $16.30

For Myesha:
At 18 hours, Myesha earns $460.80
At 22 hours, Myesha earns $563.20

Myesha's earnings per hour = (563.20-460.80)/(22-18) = $25.60

Difference in earnings per hour = Myesha's earnings per hour - Wyatt's earnings per hour = $25.60 - $16.30 = $9.30

Therefore, Myesha earns $9.30 more per hour than Wyatt.
