.06b+.12(30,000-b)=2,460
\n" ); document.write( ".06b+3600-.12b=2460
\n" ); document.write( ".06b=2460-3600
\n" ); document.write( "-.06b=-1140
\n" ); document.write( "b=-1140/-.06
\n" ); document.write( "b=19,000 is the amount invested @ 06% in bonds.
\n" ); document.write( "Proof:
\n" ); document.write( ".06*19,000+.12(30,000-19,000)=2460
\n" ); document.write( "1140+.12*1,100=2,460
\n" ); document.write( "1,140+1,320=2460
\n" ); document.write( "2,460=2,460\r
