Answer:
The correct answer is A that is $120,000.
Explanation:
The value of one or single bathroom is computed as:
Value of single bathroom = Category 2 cost - Category 1 cost
= $185,000 - $170,000
= $15,000
The value of the subject property is computed as:
Value of the subject property = Category 3 cost - Value of single bathroom
= $135,000 - $15,000
= $120,000
