Sarah is paid $15 an hour for work as a delivery driver, and $12 an hour for inventory-checking work in the warehouse. In a particular workweek, she works her first 40 hours as a driver, performs five more hours of driver work, and does five additional hours of inventory work, for a total of 50 hours.

How much may the employer pay Sarah consistently with the requirements of the federal Fair Labor Standards Act?
