Answer:
The amount of Tatoo's capital loss carryover remaining after it applies the carryback is $ 5200.
Explanation:
The net capital loss will be set off as :
2016 : $ 4800
2017 : $ 3500
Net carryback = $ 13500 - $ 4800 - $ 3500
= $ 5200
Therefore, the amount of Tatoo's capital loss carryover remaining after it applies the carryback is $ 5200.
