Please help me draw a graph similar to the one below to be able to solve part c Thank you

Suppose we are analyzing the intertemporal allocation of oil. Assume a generation is 35 years, and we are concerned with only two generations. The demand and supply functions for oil in the present generation are given by: Demand: Qd = 200-5Pa Supply: Qs = 5Ps where Q is expressed in millions of barrels and P is the price per barrel. c) Suppose that the marginal benefit function is expected to be the same for the next generation. But there is a discount rate of 4% per year, which for 35 years works out to be approximately equal to 4 = (1.04)35. Total oil supply for both generations is limited to 100 million barrels. Calculate the efficient allocation of resources between the two generations. (Hint: Draw a graph, similar to Figure 5.4 on page 115. Set the marginal net benefit equal for the two periods, remembering to include the discount rate.)
