\n" ); document.write( "6% simple interest. The account paying 12% is a higher-risk account, so she wants the
\n" ); document.write( "amount in that account to be half of the amount she has in the account paying 6% simple
\n" ); document.write( "interest. If her annual interest is $1945, how much is invested at each rate?
\n" ); document.write( "

Let amount invested at 12% be S, and the amount invested at 7%, A
\n" );
document.write( "Then amount invested at 6% is 2S
\n" );
document.write( "We then get: S + A + 2S = 25,000______3S + A = 25,000 -------- eq (i)
\n" );
document.write( "Also, .06(2S) + .07A + .12S = 1,945______.12S + .07A + .12S = 1,945_____.24S + .07A = 1,945 ------- eq (ii)
\n" );
document.write( "Solve this system to get S, or amount invested @ 12%, which is $6,500
\n" );
document.write( "Figure out the rest!! \n" );
document.write( "

\n" );
