Answer: $525,000 loss
Step-by-step explanation:
2017 taxable and financial loss = $750,000
Pretax financial income :
2015 - $300,000
2016 - $400,000
Assuming white Inc uses the carry back provision;
With tax rate for all affected period being 30%
$750,000 - (30% of $750,000)
$750,000 - (0.3 × $750,000)
$750,000 - $225,000
= $525,000 loss
