\n" ); document.write( "
\n" ); document.write( "Let x= money in a deposit at 6%
\n" ); document.write( "So, $10,000 - x= money in a mutual fund at 11%\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If we add the two investment, we get $900.00 total interest.
\n" ); document.write( "It follows,\r
\n" ); document.write( "\n" ); document.write( "\"0.06%28x%29%2B0.11%2810000-x%29=900\"
\n" ); document.write( "\"0.06x%2B1100-0.11x=900\"
\n" ); document.write( "Combine similar terms,
\n" ); document.write( "\"1100-900=0.11x-0.06x\"
\n" ); document.write( "\"200=0.05x\" ---> \"cross%28200%294000%2Fcross%280.05%29=cross%280.05%29x%2Fcross%280.05%29\"
\n" ); document.write( "x = $4,000.00, money in a deposit\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then, $10,000 - $4,000 = $6,000.00, money in a mutual fund\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Check, \"0.06%284000%29%2B0.11%286000%29=900\"
\n" ); document.write( "\"240%2B660=900\"
\n" ); document.write( "\"900=900\"\r
