To find: The total cost of the food bill.
Answer to Problem 16E
The total cost of the food bill is
Explanation of Solution
Given information: Food bill-
Calculation: The cost of the food bill=
The amount of sales tax = The cost of the food bill
The amount of the tip
The amount of sales tax and the amount of tip should be added with the cost of the food bill.
Let’s find the total cost of the food bill,
Hence, the total cost of the food bill is
