Acustomer left $3.50 as a tip. the tax on the meal was 7% and the tip was 20% of the cost including tax. what piece of information is not needed to compute the bill after tax and tip? what was the total bill?

17.50

Step-by-step explanation:

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
