Final answer:
To determine the gap to be filled by new hires, subtract the transfers out and exits from the beginning headcount. In this case, the gap is 610.
Step-by-step explanation:
To determine the gap to be filled by new hires, you need to consider the changes in headcount due to transfers and exits from the company. Starting with a beginning headcount of 800, subtract the transfers out (100) and exits (90) to get the total reduction in headcount. The formula to calculate the gap is: Gap = Beginning headcount - Transfers out - Exits.In this case, the gap to be filled by new hires would be: 800 - 100 - 90 = 610.
