Explanation:

Question: The bill for dinner was $77.12. You left $15.88 for the tip. What percentage of the original bill was the tip?

Step-by-step:

To find the percentage of how much a part ($15.88) is or a whole ($77.12), the formula of part = percentage * whole is used.

It is usually written as a = p*w

In this case, $15.88 is a and $77.12 is w.

so, 15.88 = p*77.12

However, we need to find p. To do so, we need to get p by itself. Divide 77.12 on both sides so that it cancels out on the right side.

15.88 divided by 77.12 is about 0.2059

We need to make the decimal a percentage by multiplying 100

0.2059 * 100 = 20.59%

You could probably round it up to 20.6% if you wanted to

Therefore, the tip was 20.6% or 20.59% of the original bill.
