Answer:
f(275) represents the average number of days houses stay on the market before being sold for $275,000.
Step-by-step explanation:
f(p) is defined as the average number of days that the house stay on the market before being sold as price p (in $1,000s).
Note that the mathematical equation for f(p) is not given, hence we are not given the actual relationship between price p and number of days f(p).
What we are given however is the term "f(275)".
all we can conclude from this term is that p = 275 (i.e the price sold is 275 x $1000 = $275,000). It says nothing about the actual numerical value of the number of days the house stays on the market, but leaves it as a general term f(275).
Hence the correct answer must include :
1) Selling price is $275,000
2) Number of days house stays on market averages f(275)
only the last option satisfies this:
f(275) represents the average number of days houses stay on the market before being sold for $275,000.
