Problem 5 Consider a firm with the production function Q = KL, where K is amount of capital and L is amount of labor. = 20. a) Write down the equation of the isoquant corresponding to Q Provide the plot of the isoquant, putting K on y-axis and L on x-axis. b) Write down the general equation of the isoquant corresponding to any level of output Q. c) Find the technical rate of substitution (of labor for capital) when the firm produces 20 units of output with 40 units of labor and the corre- sponding amount of capital.
