At a restaurant, the bill comes to $52. If you decide to leave a 15% tip, how much total do you need to pay? Give your answer to the nearest dollar.

Answer 1

One quick way to solve this question (and calculate tips generally) without a calculator is to use the following method:

1) Take the total and move the decimal over one place to find 10%: $52 becomes $5.2

2) Divide result by 2 to find 5%: $5.2 / 2 = $2.6

3) Add both results to find 15%: $5.2 + $2.6 = $7.8

4) Add result and total to find total amount: $7.8 + $52 = $59.8

5) Round result: $60

Answer 2

Meal Amount + Tip = Total Bill

To calculate the tip amount, you multiply 0.15 x 52

52 + 0.15(52) =

52 + 7.80 = $59.80
