Question

When Peter ate lunch at a restaurant, his food bill was $13.25. The sales tax rate was 6%. Peter left a 20% tip for the server. How much did Peter pay altogether, including tax and tip?

Answer 1

Assuming the tip is from the bill excluding the tax

he paid 13.25$ + 0.06 * 13.25$ + 0.2 * 13.25$ = 16.695$
