Question

The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.97 before the discount, 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

The discount is 15% of the cost of the meal before the discount, so the discounted cost is:

Discounted cost = $78.97 - 0.15($78.97) = $67.12

Now we need to calculate the tip on the cost before the discount. The tip is 20% of the cost before the discount, so the tip amount is:

Tip = 0.20($78.97) = $15.79

Adding the discounted cost and the tip, we get the total cost of the meal:

Total cost = $67.12 + $15.79 = $82.91

Therefore, the total cost of the meal, including the discount and tip, is $82.91.
