[email protected] 1. INTERNET TRAINING STARTUP Cecelia wants to start an Internet Training business. Based on demand, she has determined that she can charge participants $150 to attend. She does not yet have her own facility, so will have to rent a room in the beginning. She can rent a room for $1000 per session. The cost of the instructor, bringing in the equipment, and advertising is $2000 per session. Course materials, which she must provide, cost $25 per student. The room Cecelia rents can hold a maximum of 40 students. (a) Write an expression for the Cecelia’s total revenue per training session. (b) Write an expression for Cecelia’s total cost per training session. (c) How many students must Cecelia have per session to break even? (d) Create a spreadsheet to show the profit level per session for different numbers of students enrolled. (e) In the beginning, Cecelia thinks it is realistic to expect only 20 students to attend. What price should she charge them to break even? (f) If Cecelia has no other costs or revenues, how many sessions must she teach at maximum capacity to earn enough profits to invest them in obtaining her own facility, when the facility costs $210,000? (assume the original price of $150 per participant). 2. ORES R US Ores R Us (ORU) is a large international minerals company considering a bid for the exploration and mining rights on a large tract of land in the country Nova. Through contacts in the Novan Ministry of Mining, ORU has learned that a cash bid of $90 million would be “nearly certain” to win ORU these rights. Based on this information and on experience in similar situations, ORU executives believe a bid of $90 million would have a 95% chance of winning the rights. However, given Nova’s current financial situation and only moderate interest from competitors, ORU executives believe they may be able to win the rights with a lower bid. Consequently, ORU is considering two other bid levels: $40 million and $65 million, as well as not bidding at all. Analysts believes these bids would have a 33% and 75% chance, respectively, of winning the rights to this tract. ORU already knows a valuable mineral deposit lies within the tract, but the size of the deposit remains highly uncertain. Sensitivity analysis has shown that the size of the deposit is the crucial factor in evaluating the tract’s profitability — i.e., it is much more important than the other uncertainties present. Based on their analysis of available data and their professional experience, ORU’s geologists have developed the following probability estimates for the deposit: Size of Deposits Probability 20 million tons .185 40 million tons .630 80 million tons .185 Values for profit margin per unit are estimated at $4 per ton and the cost of development is estimated to be $70 million. (a) Draw the decision tree for ORU including all probabilities and payoffs. (b) Solve ORU’s decision tree. What will ORU do? (c) Is ORU happy with this outcome? Explain. (d) What, if anything, can ORU do to improve the outcome? Does this change the decision tree? Explain.
