Peter used a $5.00 gift certificate to help pay for his lunch. After adding a 15% tip to the cost of his meal, Peter still had to pay $2.36 in cash. How much did Peter's meal cost?
If the $2.36 that Peter paid was the 15% tip for the total cost of the meal, then it means:
$2.36 / .15 =$15.73 cost of the meal. However, he had $5 coupons, so the net cost to him was $15.73 + $2.36 - $5.00=$13.09.
Thanks for the help!
