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

The total cost of the lunch including the tip is $15.21.

Step-by-step explanation:

To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:

$13*17%=$2.21

Now, you need to add that amount to the price of the lunch:

$13+$2.21=$15.21

According to this, the answer is that the total cost of the lunch including the tip is $15.21.
