Which statement best describes the meaning of f(150)?

This is the average number of days the house stayed on the market before being sold for $150,000.

The house sold on the market for $150,000 and stayed on the market for an average of 150 days before being sold.

The house sold for $150,000.

The house stayed on the market for an average of 150 days before being sold.

Answer 1

The statement which best describes the meaning of f(150) is "This is the average number of days the house stayed on the market before being sold for $150,000."

Explanation:

We have given that f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s.

To find the meaning of f(150), here p= 150

which means f(150) is the average number of days a house stays on the market before being sold for price 150 in $1,000s.

And 150 in $ 1,000= $150,000

Hence, f(150) is the average number of days a house stays on the market before being sold for price $150,000.

Answer 2

The correct answer is:

This is the average number of days the house stayed on the market before being sold for $150,000.

Explanation:

f(p) is defined as the average number of days a house stays on the market before being sold for price p (given in $1000).

We want f(150); this means p=150. Since p is in thousands of dollars, this means the price of the house was $150,000.

This means f(150) is the average number of days the house stayed on the market before being sold for $150,000.
