August hosted two dinner parties for his friends. Twenty guests attended the first party, and twenty-six guests attended the second party. What is the percentage increase of the number of guests from the first party to the second party?

Answer: 30%

Step-by-step explanation:

The first step is to find the increase in numbers

26-20 = 6

Now you find the percent. This means you're looking for the percent 6 is equal to when compared to 20. The easiest way is to divide the increase by the original number

6/20 = 0.3

To convert that to percent, multiply it by 100

0.3 * 100 = 30%

There was a 30% increase.
