Joseph 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 without the tax

the total cost of the lunch, including without the tax is $15.21

Step-by-step explanation:

The cost of Joseph's lunch at the restaurant without tax is $13.00. He leaves the waiter a tip of 17% of the cost of the lunch without tax. This means that the value in dollars of the tip which he gave the waiter would be 17/100 × 13 = 0.17×13 = $2.21

The total cost of the lunch without tax would be the sum of the value of the tip and the cost of the lunch without tax. It becomes

13 + 2.21 = $15.21

the solution is 12x-6y

283 square feet
