#AAA offers 3 types of membership:

 #   Basic: 29.50 + tax per year
 #   Plus: 62.50 + tax per year
 #  Premium: 95.50 + tax per year 

#Write a program that first reads the number of family members with AAA 
#membership and the tax. Then, the program reads the type of the 
#membership for each family member. Assume that 1 idicates Basic membership, 
#2 - Plus membership, and 3 - Premium membership. 
#Assume the input is valid. The 
#program finds the total price the family pays per year and the average 
#membership price. YOU HAVE TO USE LOOP WHILE IN THIS PROGRAM.

#Functions: total(family_size, tax) - this function will read the type of 
#the membership for each family member. Function finds and returns the total 
#paid per year

#In the main we will use function total and find the average
