12,000(1+r)^(2)= 27000
\n" ); document.write( "so it's just an equation, solve it like one
\n" ); document.write( "start by dividing both sides by 12,000
\n" ); document.write( "(1+r)^2 = 2.25
\n" ); document.write( "Now get rid of that ugly square , the opposite of squaring a number, is square root, so root both sides
\n" ); document.write( "1 + r = 1.5
\n" ); document.write( "r = .5
\n" ); document.write( "so the multiplier would be 1.5 , which means he gained 50% a year\r
