#Write a function discount_price that has two parameter: original price 
#and discount percent(integer). Function returns the final price after discount 
#was applied

#Write a program (main), that fist reads the number of customers came to 
#the store. For each customer the program reads an original price. The 
#program finds the total price for all customers using the following rule: 
#price 100 dollars and below got 15% discount prices above 100 dollars got 
#25% discount In addition, program prints the discounted price for each 
#customer, and finds the average price, and the number of customers who got 
#15% discount and who got 25% discount
