Suppose that the production function for a company is given by Q = 80K 1/4 L3/4 where Q is the output (in hundreds of units), K is the capital expenditures (in thousands of dollars), and L is the work-hours. Find ∂Q/∂K and ∂Q/∂L when expenditures are $625,000 and total work-hours are 4096. Interpret the results.
