9000 * 1.06 = 9540.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's what's in the account at the end of the first year.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the 1.06 factor is derived as follows:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6% = .06\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "6% of 9000 = .06 * 9000.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "9000 + .06 * 9000 is your expression.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factor out the 9000 to get 9000 * (1 + .06) which becomes 9000 * 1.06.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the result is 9540.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the principal is 9000.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the interest is 540 which is equal to .06 * 9000.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
