A) I=prt; I=20,000(.05)(4) = $4000
b) I = prt; I = 20,000(.05)(2) = $2000
$4000-$2000 = $2000. You save $2000 by paying it off in 2 years vs. 4 years
You use Pythagorean theorem...a^2+b^2=c^2
a=12ft
b=47-31.. height of the triangle
c=distance between two roof tops
(12)^2+(16)^2=c^2
144+256=c^2
400=c^2, take square root of both sides
c=20ft

its c
