Qy = (Simplify your answer. Use integers or decimals for any numbers in the expression. Round to the nearest hundredth as needed. Type your answer using exponential notation.) b) If the factory currently uses 2,200 employees and $750,000 of capital, find the marginal productivity of labor and the marginal productivity of capital. The marginal productivity of labor is (Round to the nearest whole number as needed.) The marginal productivity of capital is (Round to two decimal places as needed.) c) Would production increase more rapidly with 500 more employees or $250,000 additional capital?A bowling ball manufacturer has the Cobb-Douglas Productivity Model Q(x,y) = 0.75xy., where x is labor (in thousands of employees); y is capital (in thousands of dollars); and Q is the number of bowling balls produced (in thousands)
