At the ice cream parlor there are thirty flavors, but for the last week they have only had 25 flavors. Find the percent of change.

Percent change = 20%

Work Shown:

A = old value = 25 (last week's number)

B = new value = 30 (current week's number)

C = percent change

C = [ (B-A)/A ] * 100%

C = [ (30-25)/25 ] * 100%

C = [ 5/25 ] * 100%

C = 0.20* 100%

C = 20%

The percent change is 20%

The positive value of C indicates we have a percent increase.

what is the original number? you forgot to add it.
