\n" ); document.write( "-------------
\n" ); document.write( "Equation:
\n" ); document.write( "int + int = interest
\n" ); document.write( "----
\n" ); document.write( "0.10x + 0.08(80,000-x) = 7800
\n" ); document.write( "-----------
\n" ); document.write( "10x + 8*80000 - 8x = 780000
\n" ); document.write( "2x = 780000-640000
\n" ); document.write( "2x = 120000
\n" ); document.write( "x = $60,000 (amt. invested at 10%)
