Answer:
decrease by $800
Explanation:
The computation of the gross profit is calculated below:
= Number of inventory units on hand at the end of the year × (Cost per unit - current replacement cost per unit)
= 200 units × ($14 - $10)
= 200 units × $4
= $800
This $800 represents the decrease in gross profit and the same is to be considered
hence, the last option is correct
