The DellaVecchia Garden Center purchases and sells Christmas trees during the holiday season. It purchases the trees for $10 each and sells them for $20 each. Any trees not sold by Christmas day are sold for $2 each to a company that makes wood chips. The garden center estimates that four levels of demand are possible:

100, 200, 500, and 1,000 trees.

a. Compute the payoffs for purchasing 100, 200, 500, or 1,000 trees for each of the four levels of demand.

b. Construct a payoff table, indicating the events and alternative courses of action.

c. Construct a decision tree.

d. Construct an opportunity loss table.
