Ms. Mills invested her $20,000 bonus in two accounts. She took a 4% loss on one investment and made a 12% profit on another investment but ended up breaking even. How much was invested in each account?

\n" ); document.write( "Equations:
\n" ); document.write( "f + t = 20,000
\n" ); document.write( "-0.04f + 0.12t = 0

\n" ); document.write( "Modify:
\n" ); document.write( "Multiply thru the top equation by 4:
\n" ); document.write( "Multiply thru the bottom equation by 100::
\n" ); document.write( "4f + 4t = 80,000
\n" ); document.write( "-4f+12t = 0
\n" ); document.write( "------------------------
\n" ); document.write( "Add and solve for \"t\":::
\n" ); document.write( "16t = 80,000
\n" ); document.write( "t = 5,000 (amt. invested at 12%)

\n" ); document.write( "f + 5000 = 20,000
\n" ); document.write( "f = 15,000 (amt. invested at 4%)
