Cheri ate lunch at a diner. The bill was $8.25. She wanted to leave a tip of 15%. Rounding to the nearest penny, how much is the tip?

Answer 1

Rounded to the nearest penny, the tip would be $1.24.

Using the mathematical formula for finding percentages of whole numbers and decimals: is/of = %/100, first you would find what 15% of $8.25 equals by cross-multiplying 15 x 8.25 = 123.75. Then you divide 123.75/100 = 1.2375 (rounded up to 1.24).

In total, when you add the tip to the original price: $8.25 + $1.49, Cheri would pay $9.49 for her delicious diner lunch!

Answer 2

8.25 x 0.1 = .825 + .825/2 = 1.24 -- Add this amount to 8.25, which equals $9.49.

A quick tip for restaurants on finding tips , 10%- shift your digits once to the right or pretend to move the decimal once to the left. if your tips are in multiples of 10, double, triple... this amount. If your percent is 15%, divide the number by two to get 5% (10% / 2 = 5%). Add both your 10% finding and 5% findings together, this is your tip, add this to your total.
