OpenStudy (perl):
the mean sale price depends on number of square feet. mean sale price = -30,000 + 7000 * ( # sq. foot )
OpenStudy (perl):
so we plug in 3000 into x
OpenStudy (perl):
and that makes sense, the average price of a home depends on how big it is
OpenStudy (anonymous):
Ok so I got 20,970,000? I got this before but thought it was wrong because of how big the number is.
