Make a decision tree for this example: Page engineering designs and contracts air conditioning and heating systems for hospitals and clinics. Currently the company staff is overloaded with design work there's a major design project due in eight weeks. The penalty for completing that design late is $$14,000$ per week, since any delay will cause a facility to open later than anticipated, and cost the client significant revenue. If the company uses its inside engineers to complete the design it will have to pay them overtime for all the work. Page has estimated that it will cost $$12,000$ per week including late weeks to have company engineers complete the design. Paige is also considering having an outside engineering firm do the design. A bit of $92,000$ has been received for the completed design. Yet another option for completing the sign is to conduct a joint design by having a third engineering company complete all electro mechanical components of the design at a cost of $$56,000$ page with then complete the rest of the design and control systems at an estimated cost of $$30,000$
