Question

Cheyenne’s total pay varies directly with the number of hours she works. If she works 5 hours, she earns $75. How much does Cheyenne earn if she works 8 hours?

Answer 1

If Cheyenne works 8 hours, she works 8/5 times as long as when she works 5 hours. Direct variation means that if she works 8/5 as many hours, she gets 8/5 as much pay.

Her earnings for 8 hours are (8/5)·$75 = $120.
