Question

dinners frequently add a 15% tip when charging a meal to a credit card. what is the price of the meal without the tip amount charged is $18.40? how much was the tip?

Answer 1

Explanation:

Let

'x' the price of the meal

15% of x or 0.15x is the tip

x + 0.15x = 20.70

1.15x = 20.70 divide both sides by 1.15

x = 20.70/1.15

x = $18

0.15*18 = $2.70

The price of the meal without the tip is $18.

The tip was $2.70.
