Joey's lunch at a restaurant cost $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?
So Joeys lunch is 13 dollars and he leaves 17 percent of that. So first we find 17 percent of 13. So 13*0.17 is equal to 2.21. So then we do 2.21+13 and we get 15.21
