B. (10 points) Accumulation and Graphical Integration and Differentiation Stocks are accumulations. The difference between the inflows and outflows of a stock accumulates, altering the level of the stock variable. The process of accumulation gives stocks inertia and memory and creates delays. Consider the following system: L R1 R2 The object of this exercises is to develop your intuition about stocks and flows. On the graph provided, draw the trajectory of the stock given the inflow and outflow rates shown. Indicate the numerical values for any maxima or minima. Assume the initial quantity in the stock is 100 units. 100 Inflow 75 Outflow Units/Time 50 25 02 0 250 5 10 15 20 200 150 Units 100 50 01 0 5 10 15 20 B.
