\n" ); document.write( "The principal gets multiplied by 1 plus the interest rate each year. You need to determine the number of years it will take $3500 to grow to $5000:

\n" ); document.write( "\"3500%281%2B.0575%29%5Ex+=+5000\"

\n" ); document.write( "The variable is in an exponent, so solve using logarithms.

\n" ); document.write( "Or on a graphing calculator graph \"3500%281.0575%5Ex%29\" and \"5000\" and find where the graphs intersect.
\n" ); document.write( "
\n" );
