Mia earns \($8.10\) per hour and worked 40 hours. Charlotte earns \($10.80\) per hour. How many hours would Charlotte need to work to equal Mia’s earnings over 40 hours?

Detailed Explanation

Begin by calculating Mia’s total earnings after 40 hours:

40 hours × 8.10 per hour = 324

Next, divide this total by Charlotte’s hourly rate to find the number of hours Charlotte would need to work:

324 ÷ 10.80 per hour = 30 hours.

40 hours × 8.10 per hour = 324

Next, divide this total by Charlotte’s hourly rate to find the number of hours Charlotte would need to work:

324 ÷ 10.80 per hour = 30 hours.
