Here the per capita income in 1985 = $7,200,

The ratio of the median sale price of an existing home to per capita income in 1980 = 6.2 (From 2nd graph)

Since it was given that the median sale price of an existing home to per capita income in 1980 is same as in 1985,

So we can write as :

median sale price of an existing home in 1985 ÷ per capita income = ratio of the median sale price of an existing home to per capita income in 1980

or median sale price of an existing home in 1985 ÷ 7200 = 6.2

or median sale price of an existing home in 1985 = 6.2 * 7200 = $44,640
