7 -22. Not wanting to leave his beloved alma mater, Will Anderson has come up with a scheme to stay around for 5 more years: He has decided to bid on the fastfood concession rights at the football stadium. He feels sure that a bid of $60,000 will win the concession, which gives him the right to sell food at football games for the next 5 years. He estimates that annual operating costs will be 40% of sales and annual sales will average $100,000. His Uncle Josh has agreed to lend him the $60,000 to make the bid. He will pay Iosh $15,400 at the end of each year. His tax rate is 15%. (a) Use a spreadsheet model to answer the following question. What is Will's average annual aftertax prot? Assume that the yearly payments of $15,400 are tax deductible. (b) Suppose that sales will probably vary plus or minus 40% from the average of $100,000 each year. Will is concerned about the minimum aftertax prot he can earn in a year. He feels that he can survive if it is at least $20,000. Model annual sales for the 5 years as ve continuous uniform random variables. Based on a sample of 7,500 veyear periods (750 periods if using Excel alone), estimate the probability that over any veyear period the minimum aftertax prot for a year will be at least $20,000. Should Will bid for the concession
