A. Consider a monopolist using one input,x, in the production process. For simplicity, assume the marginal product ofxis constant.

The monopolist faces a linear demand given by

Q=35-6P

wherePstands for the price andQstands for the quantity demanded.

Suppose the monopolist sells its product at a price of $5 per unit.

The monopolist is maximizing profits, and the marginal revenue product ofxis:

MRPx=16.7. The marginal product of the input must beMPx=______________________. (Round your answer to the nearest integer if necessary.)

B. David Ricardo modeled agricultural production as a function of one input, labor. For instance, on a typical farm, production of wheat can be represented by the functionf(x)=x, wherexis the labor input.

If the wage rate is$11, what is the cost to produce eight units of wheat?$___________________
