Question

The jayden family eats at a restaurant that is having a 15% discount promotion. their meal costs $78.78, and and they leave a 20% tip. if the tip applies to the cost of the meal before the discount, what is the total cost of the meal? round your intermediate calculations and answer to the nearest cent.

Answer 1

take 78.78 and multiply it by 20% (.2) you get 15.756 (round up to 15.76)
the family tips $15.76. add to the total. now the cost is $94.54. the discount is 15% so you multiply the total by .15. the total is $14.18. subtract that from the total plus the tip and the meal costed $79.73
