Question

The bill is 100.82. What is the amount of a 15% tip?

Answer 1

A `15%` tip would be about `$15`, or `$15.12` to be exact.

Explanation:

To find tips, multiply the value by the percent. Don't know how to find the numeric value of a percent? It is the `%` you are given over `100`.

For this example, it is `15/100`, which is `0.15` in the decimal form. Next, multiply.

`100.82 xx 0.15 = 15.123`

If you are told to round to the nearest cent, it would be `$15.12`. To the nearest `10` cents, `$15.10`. To the nearest dollar, `$15`.

To find the value of the whole thing, simply add the tip to the bill. For this example, it would end up being `$115.94`.
