Mike has a cellphone accessories shop that sells cases, memory cards, and headphones. He has a limited number of items that are available. He hired sales representatives to help him take the orders for these items. He finds that the sales representatives do a really good job on writing down the orders, but they are not good at calculating total prices to quote customers. He would like a program that will help calculate how much people owe him. He would like the program to ask the user to enter whether they want a case, memory card, or headphones. If they chose a case, the program will add $10 to the total. If they want a memory card, the program will add $20 to the total. If they chose headphones, the program will add $25 to the total. After they have entered what they want to buy, have the program ask them if they would like to order anything else. They can order as many different items as they would like. After they have ordered everything they want, the program should then tell them what their total is. If the total comes to more than $50 before taxes, they get a $5 discount. There is a 4.5% tax on the products, but no tax on the shipping. The program should print out a total amount for the customer
