Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(250)?

Houses sell for an average of $250,000.
f(250) indicates houses stay on the market an average of 250 days before being sold.
f(250) represents the average number of days houses stay on the market before being sold for $250,000.
Houses sell on the market for an average of $250,000 and stay on the market an average of 250 days before being sold.

1 answer

The statement that best describes the meaning of \( f(250) \) is:

**f(250) represents the average number of days houses stay on the market before being sold for $250,000.**

This is because \( f(p) \) is defined as the average number of days a house stays on the market before being sold at the price \( p \), where \( p \) is given in $1,000s. Therefore, \( f(250) \) specifically refers to the average number of days houses stay on the market before being sold at a price of $250,000 (\( 250 \times 1,000 \)).
