A store places orders every week and receives the orders at the start of the next week. If demand is less than the stock available, then all demand is met and the remaining stock $($known as the 'closing stock'$)$ is available for the next week. If demand exceeds supply, then any excess demand is not satisfied and the store has lost sales.

A simulation has been conducted for two weeks and is shown in the table below. Some elements of the simulation of the third week have also been completed.
