#In this program you will find a total price of the purchase based on the 
#following rule: items priced a 100 dollars and below receive 15% 
#discount. All other items receive 25% discount. Write a program that first reads one 
#integer - the number of items user purchased in the store. The program 
#then reads the price for each item. The program finds the total purchase 
#price based on the rule above. Assume the input is valid. 

#function total_price has one parameter- number of items, return total price
#after discounts are taken
