Mr. Jones has $7000 to invest. He invests part at 8% and the rest at 8.5%. The amount at 8.5% makes $65 less at the end of the year than the amount invested at 8%. What amount has he invested in each account?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt invested at 8%
\n" ); document.write( "Then
\n" ); document.write( "(7000-x) = amt invested at 8.5%
\n" ); document.write( ":
\n" ); document.write( "Interest @ 8% = Interest @ 8.5% + $65
\n" ); document.write( ".08x = .085(7000-x) + 65
\n" ); document.write( ";
\n" ); document.write( "Find x
\n" ); document.write( "
\n" );
