\n" ); document.write( "

\n" );
document.write( "Then amount invested at 5% is: 21,000 - S
\n" );
document.write( "We then get: .06S + .05(21,000 - S) = 1,180
\n" );
document.write( ".06S + 1,050 - .05S = 1,180
\n" );
document.write( ".01S = 130
\n" );
document.write( "Amount invested at 6%, or 
\n" );
document.write( "Based on provided info, do you think you can find the amount invested at 5%? \n" );
