Identify the classes and associations in the following narrative and draw a class diagram with multiplicities (25% of Grade): To put himself through school, Zach operates an ice cream truck that travels through neighborhoods, ringing a bell to attract kids that want a cold ice cream treat. Zachs inventory includes many ice cream products and he tracks which items are sold in each sale. He occasionally adds new items to his list of ice cream products for sale. Zach only accepts cash for each sale. To identify the routes that generate the most sales, Zach summarizes sales by neighborhood but he only tracks neighborhoods with at least one sale. Zach deposits the cash received in his bank account at the end of each day. (Hint: There is only one agent for this diagram Neighbor)
