Assume that a firm uses labor and capital to produce a product. The firm hires labor at a wage rate of $4 per unit and rents capital at $5 per unit.

To minimize its cost of production without changing the level of output, the firm should a.) make no changes b.) hire more labor and rent more captital c.) hire less labor and rent more capital d.) hire more labor and rent less capital Hire less labor and rent less capital

Aproduct has a demand of 4000 units per year. ordering cost is $20, and holding cost is $4 per unit per year. the cost-minimizing solution for this product is to order: ? a. 200 units per order. b. all 4000 units at one time. c. every 20 days. d. 10 times per year. e. none of the above
