Dasia earns $9.50 per hour. She worked 8 hours. She decided to save ¹/₅ of his earnings. How much did Dasia have left after saving?

Answer explanation

If your answer was 15.20, then your math is fine, but you answered how much was saved rather than how much was kept.

The problem is 9.5 * 8 = earned money. (76)

Saving 1/5 means that we kept 4/5.

76 * 0.8 = 60.80

or

76 * 4 = 304 / 5 = 60.80
