A consumer is trying to decide between two long-distance calling plans. The first charges a flat rate of 10¢ ($0.10) per minute, whereas the second charges a flat rate of 99¢ ($0.99) for calls up to 20 minutes in duration and then 10¢ ($0.10) for each additional minute exceeding 20 (assume that calls lasting a non-integer number of minutes are charged proportionately to a whole-minutes charge). Suppose the consumer's distribution of call duration is exponential with parameter λ.
a. Explain intuitively how the choice of calling plan should depend on what the expected call duration is.
b. Which plan is better if expected call duration is 10 minutes? 15 minutes? [Hint: Let h1(x) denote the cost for the first plan when call duration is x minutes and let h2(x) be the cost function for the second plan. Give expressions for these two cost functions, and then determine the expected cost for each plan.]
