Answer:
14.06%
Step-by-step explanation:
To find the percent increase, find the difference between the original and new amounts, divide it by the original amount, then multiply by 100:
73 - 64 = 9, so the difference is 9.
Divide this by the original and multiply by 100:
(9 / 64) x 100
= 14.06
So, the percent increase in the membership is 14.06%
