The correct answer for the question that is being presented above is this one:
Based on the table that is shown from my research, 
As it stands now, the total cost in millions of dollars is:

47.0 + 2.5 = 49.5

Now, if half of the full-time workers become part time, then the total cost will be

= 47.0 * [(1740 − 0.5 * 1740) /1740] + 2.5 * [(170 + 0.5 * 1740) / 170]
= 23.50 + 15.29
= 38.79
Then the answer will be 38.79
