1. The demand equation for a monopolist's product is p = 200 -0.98q, where p is the price per unit (in dollars) of producing q units. If the total cost c (in dollars) of producing q units is given by C = 0.02q² + 2q + 8000. Find the level of production at which profit is maximized. S = 1+√1-6 √I+3 2. Suppose that the saving function of a country is given by: where the national income (1) and the national saving (S) are measured in billions of dollars. Determine the country's marginal propensities to consume and its marginal propensities to save when the national income is $121 billions.
