Assume that the oil extraction company needs to extract Q units of oil (a depletable resource) reserve between two periods in a dynamically efficient manner. What should be a maximum amount of Q so that the entire oil reserve is extracted only during the 1st period if (a) the marginal willingness to pay for oil in each period is given by P = 33 - 0.5q, (b) marginal cost of extraction is constant at $3 per unit, and (c) discount rate is 1%?

Please solve clearly.
