The owners of an apartment building bought it new and then 2 years later sold it for $120000. They calculated that the building appreciated $10000 per year while they owned it.

Find a linear function that describes the value of the building over time, if

is the age of the apartment building.

V (x) =

The correct answer is V (x) = 100,000 + 10,000x

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Price of the apartment after 2 years = US$ 120,000

Calculated appreciation of the apartment annually = US$ 10,000

2. Find a linear function that describes the value of the building over time, if x is the age of the apartment building.

V (x) = Original price of the apartment + Annual appreciation * Age of the apartment in years

Original price of the apartment = 120,000 - 2 * 10,000

Original price of the apartment = 120,000 - 20,000

Original price of the apartment = 100,000

Now, replacing with the values we know to build the linear function, we have:

V (x) = 100,000 + 10,000x
