Question

A restaurant customer left $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax.

Answer 1

17.50

Step-by-step explanation:

you really don't need to know the tax amount.

20% of x = 3.50

(20/100) x = 3.50 Divide top and bottom of the left number by 20

(20÷20) / (100÷20) * x = 3.50

(1/5) x = 3.50 Multiply both sides by 5

x = 3.50 * 5

x = 17.50

The meal cost 17.50
