\n" ); document.write( ":
\n" ); document.write( "Let t = no. of weeks for this to happen
\n" ); document.write( ":
\n" ); document.write( "Treat this like compound interest:
\n" ); document.write( "60*(1.08)^t = 132
\n" ); document.write( ":
\n" ); document.write( "1.08^t = \"132%2F60\"
\n" ); document.write( ":
\n" ); document.write( "1.08^t = 2.2
\n" ); document.write( ":
\n" ); document.write( "t*log(1.08) = log(2.2)
\n" ); document.write( ":
\n" ); document.write( ".03342t = .34242
\n" ); document.write( "t = \".34343%2F.03342\"
\n" ); document.write( "t = 10.25 weeks
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check on a calc enter: 60*1.08^10.25 = 132.0 \n" ); document.write( "
