Suppose men receive $6 per hour and women receive $5.50 per hour. Moreover, suppose the firm uses 400 person-hours of W and 625 person-hours of M to produce 10,000 units of output.

Is this firm minimizing the cost of producing this given level of output? If not, explain what this firm should do?

How should i approach this question?
