Paula must have some wonderful information if she is getting an 11% return!
\n" ); document.write( ".
\n" ); document.write( "(x * 0.11) + [(x+4000)* .06] = 665
\n" ); document.write( "Distribute
\n" ); document.write( "0.11x + .06x + 240 = 665
\n" ); document.write( "Add
\n" ); document.write( "0.17x + 240 = 665
\n" ); document.write( "Subtract
\n" ); document.write( "0.17x = 425
\n" ); document.write( "Divide
\n" ); document.write( "x = 2500
\n" ); document.write( ".
\n" ); document.write( "Let's see if that's right.
\n" ); document.write( "2500 * .11 = 275
\n" ); document.write( "6500 * .06 = 390
\n" ); document.write( "Add them together to get $665
\n" ); document.write( "Success!
\n" ); document.write( "
\n" );
