Question: OPTIMAL SELLING TIME The present value of a piece of waterfront property purchased by an investor is given by the function
P(t) = 80,000e√t/2 - 0.09t (0 ≤ t ≤ 8)
Where P(t) is measured in dollars and t is the time in years from the present. Determine the optimal time (based on present value) for the investor to sell the property. What is the property's optimal present value?
