Answer:
Step-by-step explanation:
From the question, a room adds $20,000 to the value of a house.
Comparable B is a 4 bedroom house with no swimming pool right,
Now if Comparable B was a 3 bedroom house instead of a 4 Bedroom we will have
= $280,000 - $20,000
= $260,000
This simply says that the value of Comparable B is $260,000 because it has 3 bedrooms and this value should be the same for any other house with 3bedrooms.
Therefore the difference between Comparable A that has a 3 bedrooms also but is valued at $275,000 and comparable B is the swimming pool.
Hence the value for the swimming pool will be
= 275,000 - 260,000
= $15,000
Therefore the value of the pool is $15,000.
