remain = change % 100

quarters = remain // 25

print(quarters, 'quarters', end = (','))

tryDimes= remain - quarters * 25

dimes = tryDimes //10

print(dimes, 'dimes', end = (','))

tryNickels = tryDimes % 10

nickels = tryNickels //5

print(nickels, 'nickles', end = (','))

pennies = tryNickels % 5

print(pennies, 'pennies')

cost = int(input("Enter the cost of the item: " ))

tender = int(input("Enter the amount tendered: " ))

makeChange(cost, tender)
