I can't figure this one out...

Emil Hansen is interested in leasing a sports-utility vehicle and has contacted three automobile dealers for pricing information. Each dealer offered Emil 24-month lease with no down payment due at the time of signing. Each lease includes a monthly cost, mileage allowances, and the cost for additional miles and the details are given in the below table.

DEALER	MONTHLY COST	MILEAGE ALLOWANCE	COST PER ADDITIONAL MILE
True Vehicle	300	40000	0.30
FCO	360	46000	0.35
Jacks Auto	410	50000	0.15

Emil decided to choose the lease option that will minimize his total 24-month cost. Emil is not sure how many miles he will drive in the next two years. Hence, for the purpose of decision, assume that Emil wants to evaluate options of driving 20,000 miles per year, 23,000 miles per year, and 25,000 miles per year.

The payoff table for the cost is:

	ACTUAL miles driven annually
Dealer	20000	23000	25000
True Vehicle	7200	9000	10200
FCO	8640	8640	10040
Jacks Auto	9840	9840	9840

It wants me to construct a decision tree based on the payoff table constructed above.
