** Question 12**

** 0 / 1 point**

You estimate a short-run production function to be Q = 16L0.8 which gives a Marginal Product of Labor function MPL = 0.8*16L-0.2 = 12.8/L0.2 If the product made by the labor sells at a price P=$8 per unit, then the Marginal Revenue Product of Labor MRPL for the 100th labor unit is ______. If labor costs wage = $46 per labor unit, then the firm ______ hire the 100th labor unit.
