Question

A waiter received a $5.25 tip. If the check totaled $25, what percentage was received?

Answer 1

This was a 21% tip.

Explanation:

The percentage of the tip, let's call it `p`, is calculated by dividing the amount of the tip, let's call it `t` by the total amount of the bill, let's call it `b` and multiplying it by 100. The formula for this is:

`p = t/b * 100`

Because we know the amount of the tip and the amount of the bill we can substitute these numbers and solve for `p`:

`p = ($5.25)/($25.00) * 100`

`p = ($525.00)/($25.00)`

`p = 21`
