Question:

Answer the questions in Exercise 35 for an oil field with a pumping rate of P'(t) = 1.2e0.02t and with a reserve of 12 billion barrels. Assume that the prevailing interest rate is 5% as before, but that the price of oil after t years is given by A(t) = 112e0.015t.

Data from Exercises 35

Oil is being pumped from an oil field t years after its opening at the rate of P'(t) = 1.3e0.04t billion barrels per year. The field has a reserve of 20 billion barrels, and the price of oil holds steady at $112 per barrel.

a. Find P(t), the amount of oil pumped from the field at time t. How much oil is pumped from the field during the first 3 years of operation? The next 3 years?

b. For how many years T does the field operate before it runs dry?

c. If the prevailing annual interest rate stays fixed at 5% compounded continuously, what is the present value of the continuous income stream V = 112P(t) over the period of operation of the field 0 ≤ t ≤ T?
