Answer:
Another Copier
Step-by-step explanation:
Based on the information provided I would recommend that the company buy another copier as it provides the greatest benefit for the cost. For example, five workers are able to increase production by 50,000 pages per day. This means that 1 worker increases production by 10,000 pages per day, while one copier increases production by 50,000 per day.
Now 1 copier is worth 2 workers (double what a single worker costs), but two workers only increase production by 20,000 pages per day which is still 30,000 pages less per day than the copier. Therefore, the copier would provide the greatest benefit to the company.
