\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Eq. ::::x + y = 22000
\n" ); document.write( "----------
\n" ); document.write( "Interest Eq. ::: 0.035x + 0.05y = 890
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Multiply thru Quantity by 500
\n" ); document.write( "Multiply thru Value by 1000
\n" ); document.write( "-------------------------------------
\n" ); document.write( "50x + 50y = 50*22000
\n" ); document.write( "35x + 50y = 1000*890
\n" ); document.write( "-------------------------------------
\n" ); document.write( "15x = 210,000
\n" ); document.write( "x = $14,000 (amt. invested at 3.5%)
