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?
