Fred earns $6.50 an hour, plus tips, as a waiter. Suppose he works 26 hours in a week. How much money must he receive in tips to earn at least $229 that week?

Respuesta :

$60. 26 x 6.50 = $169. 229 - 169 = 60.
Simply multiply $6.50 by 26 to get $169.
The rest of the money he made was in tips.
Therefore, $229-$169 = $60 in tips.
