Two investments earn an annual income of $575. One investment earns an annual simple interest rate of 8.5%, and the other investment earns an annual simple interest rate of 6.4%. the amount invested is $8000. How much is invested in each account?\r
\n" ); document.write( "\n" ); document.write( "let the amount given for 8.5 % simple interest be x.
\n" ); document.write( "Then it is obvious that the other amount is 8000-x.\r
\n" ); document.write( "\n" ); document.write( "Interest earned on first amount = ptr/100 = x*1*8.5/100.
\n" ); document.write( "Interest earned on second amount = ptr/100 = 8000-x*1*6.4 / 100\r
\n" ); document.write( "\n" ); document.write( "so the total interest is 8.5x/100 + 6.4*(8000-x)/100\r
\n" ); document.write( "\n" ); document.write( "(8.5x+51200-6.4x) = 575*100\r
\n" ); document.write( "\n" ); document.write( "2.1x = 57500-51200 = 6300 ----> x= 6300/2.1 =3000.\r
\n" ); document.write( "\n" ); document.write( "So the first amount is $3000. and second amount is $5000
