The Striton family had a meal catered for a wedding rehearsal dinner. The cost of the dinner was $476. There was a 5% sales tax and they left a 15% tip. What was the total cost including the sales tax and the tip?

Answer 1

Julia Adams

$571.20

The dinner itself = $476

The tax = 5% of $476 =$ 476 x 0.05

The tip = 15% of $476 =$ 476 x 0.15

Total them all up:

(571.20) = (476) + (476 x 0.05) + (476 x 0.15)

Whether you tip on the entire bill with tax or before tax—I tipped before tax—will affect the answer.
