(Q1)  Many software companies, after years of providing unlimited free telephone technical support for their products, began to charge for these services (typically after an initial start-up period of 90 days). Most companies offer two pricing plans. For instance, Lotus Development offers users of their spreadsheet software the option of paying either (i) $2.00 per minute for telephone support or (ii) a $129 flat charge for a year of unlimited toll-free calls. Question 1: Consider a customer with a yearly (expected) demand for service support of P = 11 – 0.1Q, where P is the price per minute and Q is the number of minutes of calls made per year. How many calls would this customer make under plan (i)? Why? How many calls would he or she make under plan (ii)? What would be the annual cost to this customer under each plan? Explain your answer. Question 2: Which plan would this customer choose? Explain your answer.
