Let x be part of the $120,000 we wish to invest under 5% interest.\r \n" ); document.write( "\n" ); document.write( "120000-x will be the other part of our $120,000 that we invest in the low-risk stock that earns 1%. With that we can set up our equation.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( ".05x + (120000-x)*.01 = 4400\r \n" ); document.write( "\n" ); document.write( ".05x + 1200 - .01x = 4400\r \n" ); document.write( "\n" ); document.write( ".04x = 3200\r \n" ); document.write( "\n" ); document.write( "x = 80000\r \n" ); document.write( "\n" ); document.write( "120000-x = 120000-80000 = 40000\r \n" ); document.write( "\n" ); document.write( "5% : 80000 \n" ); document.write( "1% : 40000\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
