You can put this solution on YOUR website!
let the amount invested in bonds yielding 3% be x
\n" ); document.write( "then twice as much invested in bonds yielding 5% will be 2x.
\n" ); document.write( "the number of years is 1.
\n" ); document.write( "simple interest for 3% bond = (x*1*3)/100 => 3x/100
\n" ); document.write( "simple interest for 5% bond = (2x*1*5)/100 => 10X/100
\n" ); document.write( "Given that the total income of the investments was 208, then
\n" ); document.write( "3X/100 + 10X/100 = 208\r
\n" ); document.write( "\n" ); document.write( "3x+10x = 20800
\n" ); document.write( "13x = 20800
\n" ); document.write( "x=1600
\n" ); document.write( "therefore the money invested at 3% interest is $1,600 and money invested in 5% is 2*1600 = $3,200.
\n" ); document.write( "
\n" ); document.write( "
\n" );
