Vending Machine Business Problem Statement. The business's products are chips and sodas.

They want us to write an app that stores their inventory and displays it to the user, including the unit price of each product, and how many items are left of the product. The user can then select a product, insert money (by keying in the amount), and get the selected item dispensed if the amount is right and if the product is not out of stock. The app must return the change if the amount entered is above the items unit price. The app must redisplay the updated inventory to allow the user to buy again. The app must update the amount of money that it has collected so far.
