ou have this short run production function where Labor is the only variable input: Q = (-.01)*L3 + (.5)*L2 Remember that marginal product (MP) is the first derivative of the production function. Take the first derivative of this function and then tell me the value of MP for the 10th worker. (Simply plug "10" into the derivative for "L" and solve.) Multiple Choice The marginal product of the 10th worker is 18 The marginal product of the 10th worker is 14 The marginal product of the 10th worker is 11 The marginal product of the 10th worker is 7
