Answer:

The answer to your question is 25%

Step-by-step explanation:

Data

Initial price = $2.00

Final price = $2.50

First we subtract the final price to the inicial price

              increment = 2.50 - 2.00

                                = $0.50    It's the amount that the school increases to the community members

            Now we use a rule of three to find the percent

                 $2.00 ----------------------  100%

                 $0.50  ---------------------    x

x = 0.50 x 100/2 = 50/2 = 25%
