\n" ); document.write( "-------------
\n" ); document.write( "EQUATIONS:
\n" ); document.write( "Quantity: x + y = 16000
\n" ); document.write( "Interest: 0.04x + 0.06y = 760
\n" ); document.write( "-------------------
\n" ); document.write( "y = 16000-x
\n" ); document.write( "Substitute:
\n" ); document.write( "0.04x + 0.06(1-6000-x) = 760
\n" ); document.write( "4x + 6(16000-x) = 76000
\n" ); document.write( "-2x = 76000-6*16000
\n" ); document.write( "2x = 20000
\n" ); document.write( "x = $10,000 (amount invested at 4%)
\n" ); document.write( "-------------
\n" ); document.write( "16000-x = $6,000 (amount invested at 6%
\n" ); document.write( "------------
