Answer:
Gain= $400,600
Step-by-step explanation:
First, we need to calculate the book value of the building:
Book value= purchase price - accumulated depreciation
Book value= 599,900 - 200,300
Book value= $399,600
If the selling price is higher than the book value, the company gain from the sale.
Gain/loss= selling price - book value
Gain/loss= 800,200 - 399,600
Gain= $400,600
