Draw a decision tree for Rich’s firm. What are the nine possible outcomes Rich is facing?
What is the profit (Revenue - fixed costs) associated with each of the nine outcomes? Be sure to consider the capacity limits of each alternative when calculating revenues.
Rich Sawyer runs a landscaping firm. Each year Rich contracts for labor and equipment hours from a local construction company. The construction company has given Rich three different capacity options:

Once Rich has chosen a capacity option, he cannot change it later. In addition, the cost for each capacity option is fixed. That is, Rich must pay for all labor and equipment hours he contracts for, even if he doesn’t need them all. Therefore, there are essentially no variable costs. Rich also has information concerning the amount of revenue and the labor and equipment hours needed for the “typical” landscaping job:
Job revenue.......$2,000 per job
Labor hours per job....30 hours
Equipment hours per job... 20 hours
Finally, Rich has identified three possible demand levels. These demand levels, with their associated probabilities, are as follows:

Y LABOR EQUIPMENT OPTION HOURS HOURS High capacity Medium capacity Low capacity 9,000 6,750 4,500 6,000 4,500 3,000 $10 per hour Cost per labor hour: Cost per equipment hour: $20 per hour
