The labor force at the beginning of the year is 15,000 workers. Then in the current year, 750 new workers enter the labor force, so the total labor force becomes:
15,000 + 750 = 15,750
Then in the current year, some workers leave the labor force, and some others re-enter the labor force. The net increase or decrease in the labor force is:
705 - 600 = 105
This means that at the end of the year, the labor force will have 105 more workers than at the beginning of the year. Therefore:
15,750 + 105 = 15,855
However, the question asks for the labor force at the end of the year after the 1400 workers have found jobs and are no longer unemployed. Therefore, we need to subtract those 1400 workers from the labor force:
15,855 - 1400 = 14,455
However, the question asks for the labor force at the end of the year, including both employed and unemployed workers. Therefore, we need to add the number of unemployed workers, which is 100:
14,455 + 100 = 14,555
Finally, we round to the nearest whole number to get:
Labor force will consist of 15,450 workers.
