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

Nov 14, 2016

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:

$p = \frac{t}{b} \cdot 100$

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)

$p = 21$
