Question

August hosted two dinner parties for his friends. Twenty-five guests attended the

first party, and twenty-seven guests attended the second party. What is the
percentage increase of the number of guests form the first party to the second
party?

Answer 1

8%

Explanation:

Percent change = 27 - 25

|25|

x 100 = 2

25

x 100 = 8 % (increase)

Where: 25 is the old value and 27 is the new value. In this case we have a positive change (increase) of 8 percent because the new value is greater than the old value.

Answer 2

There is an 8% increase

Explanation:

The formula to find percent change is

%change =
`(new-original)/(original)` x 100

So input the values that you have to get

%change =
`(27-25)/(25)` x 100

Now finish solving to get

% change =
`(2)/(25)` x 100

%change = 0.08 x 100

%change = 8%
