Question

Joseph’s lunch at a restaurant costs $13.00, without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip without tax? *

Answer 1

17% of 13 is 2.21

13 + 2.21 = 15.21

Explanation:

Joseph's lunch costs = $13 without taxes

He leaves tip for the waiter = 17% of cost of the lunch

= 17% of $13

= 13 ×

= ( 13 × 0.17)

= $2.21

Total cost of lunch + tip = 13 + 2.21

= $15.21
