Joe the owner of the ice cream shop, purchases ice cream from two vendors. Over the
years, he has developed good relationships with both vendors so they allow Joe to pay them
biweekly for all purchases made during the preceding two-week period. Joe calls in ice-
cream orders on Mondays and Thrusdays. The orders are delivered the next day. Joe buys
ice-cream toppings from one of several local stores and pays for each such purchase at the
time of sale with a check from the company's main checking account. Draw
an REA diagram, complete with cardinalities, for Joe's expenditure cycle.
