Question

A restaurant customer left a $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax. (Complete the next two questions) A) What piece of information is not needed to compute the bill after tax and tip? B) What was the total bill?

Answer 1

Answer: 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

A) "The tax on the meal was 7%" is not needed to compute the bill after tax and tip.

B) The total bill was $17.50

Step-by-step explanation: 3.50/.20=17.5
