What is the total cost of a 65$ meal with 8% sales tax and a 15% tip

The total cost of the meal would be $86.20. This is calculated by first adding the 8% sales tax to the original cost of the meal, which would be $65 + ($65 x 0.08) = $70.20. Then, the 15% tip is added to the total cost, which would be $70.20 + ($70.20 x 0.15) = $86.20.
