Jamal and his family went to their favorite restaurant
for dinner. The cost of the dinner was $86.90. The
family used a $15.00 off coupon, which discounted from
the total cost of the dinner. Jamal left the waiter an
18% tip of the discounted bill. How much did the family
pay for dinner, including discount and tip?

Respuesta :

86.90 - 15.00 = 71.9
71.9 * .18 = ~ 12.94
71.9 + 12.94 = $84.84
