Question 1:

A t shirt company is planning a production run for an event where the attendance (and thus demand for t-shirts) is uncertain. The event planners have indicated that they think the attendance will be 500, 750 or 1000, with probabilities of 30%, 50% and 20% respectively. The company must pre-order the blank t-shirts (cost=\$5 per shirt) and it can sell finished shirts for \$12 apiece. Any finished shirts that cannot be sold at the event can be sold for \$2 apiece to a used clothing vendor.

A)    What Excel function is useful for calculating the expected value of demand for t-shirts? What is the expected demand?

B) What Excel function is useful for calculating revenue? Explain why it is useful.

C) What are the two possible cases for the amount of t-shirts that will be sold to the used clothing vendor? How would you calculate this amount in a spreadsheet model?

D) Suppose that blank t-shirts can only be ordered from the wholesale vendor in batches of 100? How many t-shirts should the company order?

E) Suppose now that blank t-shirts can only be ordered from the wholesale vendor in batches of 50? How many t-shirts should the company order?
