A copy company wants to expand production. It currently has 20 workers who share eight copiers. Two

months ago, the firm added two copiers, and output increased by 100,000 pages per day. One month

ago, they added five workers, and productivity also increased by 50,000 pages per day. Copiers cost

about twice as much as workers. Would you recommend they hire another employee or buy another

copier? I know how to find the marginal productivity of the copier and the workers but i am having a difficult time calculating the additional copier and addition worker.
