\n" ); document.write( "On two investments totaling $7,000, Lydia lost 4% on one and earned 6% on the other. If her net annual receipts were $308, how much was each investment?
\n" ); document.write( "

Let amount invested in fund that lost 4% be F
\n" );
document.write( "Then amount invested in fund that gained 6% = 7,000 - F
\n" );
document.write( "We then get: - .04F + .06(7,000 - F) = 308
\n" );
document.write( "- .04F + 420 - .06F = 308
\n" );
document.write( "- .1F = - 112
\n" );
document.write( "F, or amount invested in fund that LOST 4%: 
\n" );
document.write( "Amount invested in fund that GAINED 6%:  \n" );
document.write( "

\n" );
