Comprehensive and Detailed in Depth Explanation:

The cost per hire is calculated by dividing the total recruitment cost by the number of hires. The formula is:

Cost per hire = Total recruitment cost ÷ Number of hires.

Cost per hire = $200,000 ÷ 50 = $4,000.

The average recruitment timeline (100 days) is not relevant to this calculation. Thus, the cost per hire is $4,000. This metric is commonly used in HR to evaluate recruitment efficiency.
