The median size of a new house grew from 1780ft in 1997 to 2223ft in 2008. What is the percent of increase?

USPshnik [31]

So we know that 1780ft was the original thus it's = to a hundred percent. To find the percentage increase, first look at the increase in general 2223-1780= 480ft. So now we know the median increased by 480ft. So to express that as a percentage we can write the equation

X/100 = 480/1780
X = (480 • 100)/1780
X = 26.9662921%

X = 26.97 %

So the % increase is 26.97%
