This program is supposed to enter the total, enter the amount the customer paid, calculate the change and tell how many dollars, quartes, nickels and pennies. The program has an error when I tried to calculate the total=5.67 and the amount paid=15.00 the change=9.39 Now Dollars=9, quarters=1,dimes=0, nickels=1,now her is the problem it gives me pennies=2 instead of pennies=3 This is what I Have and what do I have to change.
