Amy Lloyd is interested in leasing a new car and has contacted three automobile dealers for pricing information. Each dealer offered Amy a closed-end 36 month lease with no down payment due at the time of signing. Each lease includes a monthly charge and a mileage allowance. Additional miles receive a surcharge on a per-mile basis. The monthly lease cost, the mileage allowance, and the cost for additional miles follow: Dealer Monthly Cost Mileage Cost per Allowance Additional Mile $289 35,000 $0.15 Dealer Dealer B Dealer $300 45.000 $0.20 5315 54,000 $0.15 Amy decided to choose the lease option that will minimize her total 36- month cost. The difficulty is that Amy is not sure how many miles she will drive over the next three years. For purposes of this decision she believes it is reasonable to assume that she will drive 12,000 miles per year, 15,000 miles per year, or 18,000 miles per year. With this assumption Amy estimated her total costs for the three lease options. For example, she figures that the Dealer Alease will cost her 36($289) + $0.15(36,000 - 36,000) - $10,404 if she drives 12,000 miles per year 36(5289) - $0.15[45,000 - 36,000) - $11.754 if she drives 15,000 miles per year, or 36($289) + $0.15(54,000 - 36,000) - $13,104 if she drives 18,000 miles per year. (a) What is the decision, and what is the chance event? The decision is to choose the best lose option alternatives. The chance event is the number of mes driven There are possible outcomes (b) Construct a payoff table. Enter your answers in $).

The recommended decision using the optimistic approach is Dealer The recommended decision using the conservative approach is Dealer Aura |x The recommended decision using the minimax regret approach is Dear G (d) Suppose that the probabilities that Amy drives 12,000, 15,000, and 18,000 miles per year are 0.5, 0.4 and 0.1, respectively. What option should Amy choose using the expected value approach? EVIDealer A) - 11214 EV(Dealer B) - $ 10980 EVIDealer C) - $ 11340 The best decision is Dealer B (e) Develop a risk profile for the decision selected in part (d). What is the most likely cost, and what is its probability? Based on the risk profile, the most likely cost is s at a probability of (6) Suppose that after further consideration Army concludes that the probabilities that she will drive 12,000, 15,000, and 18,000 miles per year are 0.3, 0.4, and 0.3, respectively. What decision should Amy make using the expected value approach? EV Dealer A) - 5 EV(Dealer B) - 5 EVIDealer C) = $ The best decision is S
