Lanie has been sick and was only able to work 4/5 of her usual 40-hour week. If her hourly rate is $15, how much was her salary for that week? Think carefully first, then make a decision:
Lanie was only able to work for 40 * 4 / 5 = 32 hours in that week. Thus, her salary was 15 * 32 = $480. So, the answer is 480.
