A total of $10,000 was invested in two bond mutual funds, a junk bond fund and a government bond fund.
\n" ); document.write( "j + g = 10000
\n" ); document.write( "---------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " The junk fund is risky and yields 11% interest. The safer government bond fund yields only 5%. The year’s total income from the two investments was $740.
\n" ); document.write( "0.11j + 0.05g = 740
\n" ); document.write( "------------------------\r
\n" ); document.write( "\n" ); document.write( " How much was invested in each fund?
\n" ); document.write( "---------------------------
\n" ); document.write( "Rearrange for elimination:
\n" ); document.write( "5j + 5g = 50000
\n" ); document.write( "11j+ 5g = 74000
\n" ); document.write( "-----------------------
\n" ); document.write( "Subtract 1st from 2nd:
\n" ); document.write( "6j = 24000
\n" ); document.write( "j = $4000 (amount invested in junk)
\n" ); document.write( "Since j+g= 10000, g = $6000
\n" ); document.write( "================================
