Question

7. A group of friends orders pizza at a restaurant. Each person gives some money to Chris before they order.

a. Chris has $63 to spend on the order, including tax. The tax at the restaurant is 5%. What is the maximum cost of food the group can order and not go over $63? Explain your reasoning.

b. Chris wants to leave a 15% tip on the price of the food, calculated before sales tax. What is the maximum cost of food the group can order and not go over $63? Explain.

Answer 1

The answer to a is: 59.85$ because 5% of 63$ is 3.15$ so take away 3.15 from 63 and you you 59.85

The answer to B is: 53.55$ because 15% of 63$ is 9.45$ so once again do the same thing you did to A and take away 9.45$ from 63$ and you get 53.55
