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?

A 30
Explaination
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.
