\n" ); document.write( ":
\n" ); document.write( "let t = time for this to happen
\n" ); document.write( "1.055^t = 2
\n" ); document.write( "Use logs
\n" ); document.write( "t*log(1.055) = log(2)
\n" ); document.write( "use your calc
\n" ); document.write( "t = \"log%282%29%2Flog%281.055%29\"
\n" ); document.write( "t = 12.946 ~ 13 years
