Question

As a valet at the mall, Davis works 8-hour shifts. He earns $4 per hour and keeps 90% of his tip money. How much does Davis need to be tipped so that he takes home exactly $100.00, before taxes are deducted, per shift?

Answer 1

Money earned: 8*4 = $32

Tips needed: 100-32 = $68

If he keeps 90%, the total money he needs to earn in tips is (10/9)*68 = $75.55
