A waitress at a local restaurant earns $3.25 per hour plus tips. In two weeks she earned a total of $720, including $531.50 in tips. How many hours did the waitress work during this 2-week period?
Subtract the tips from the total earned to get the base pay:
$720.00 - $531.50 = $188.50
Since she makes a base salary of $3.25, divide $188.50 b $3.25 to get the number of hours worked:
$188.50 ÷ $3.25 = 58 hours.
