Solve the problem.It is estimated that the total value of a stamp collection is given by the formula  where t is the number of years from now. If the inflation rate is running continuously at 4% per year so that the (discounted) present value of an item that will be worth $v in t years' time is given by Sketch the graph of the discounted value as a function of time at which the stamp collection is sold. The graph has an absolute maximum. What is the value of t at the absolute maximum? What is the discounted value of the collection at that time?
