An investor has a total of $25,000 deposited in three different accounts, which earn annual interest rates of 8%, 6%, and 4%. The amount deposited in the 8% account is twice the amount in the 6% account. If the three accounts earn total interest of $1,520, how much money is deposited in each account.\r
\n" ); document.write( "\n" ); document.write( "let amount invested at 6% be x
\n" ); document.write( "8%-----------2x\r
\n" ); document.write( "\n" ); document.write( "Balance at 4%\r
\n" ); document.write( "\n" ); document.write( "4%-----------(25000-3x)\r
\n" ); document.write( "\n" ); document.write( "6%*x +8%*2x +4%(25000-3x)=1520\r
\n" ); document.write( "\n" ); document.write( "multiply equation by 100\r
\n" ); document.write( "\n" ); document.write( "6x+16x+100,000-12x=152000\r
\n" ); document.write( "\n" ); document.write( "10x=152000-100000\r
\n" ); document.write( "\n" ); document.write( "10x=52000
\n" ); document.write( "x= 5,200-----------6%
\n" ); document.write( "2x=10,400----------8%
\n" ); document.write( "8,400--------------4%\r
\n" ); document.write( "\n" ); document.write( "Check\r
\n" ); document.write( "\n" ); document.write( "6%*5,200 +8%*10,400 +4%*9,400= 1520\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
