Answer:
There is something wrong with this question because October to February is not four months, it's five months.
We can calculate this assuming 3 months of 2016 (October, November, December) and 2 months of 2016 (November and December).
- 3 months of 2016 = ($22,400 / 4 months) x 3 months = $16,800
- 2 months of 2016 = ($22,400 / 4 months) x 2 months = $11,200
No option is correct.
