let a= part at 7%
\n" ); document.write( "b= part at 6%
\n" ); document.write( "b=80000-a
\n" ); document.write( "That simple subtraction is the part that throws most people.
\n" ); document.write( "7%(a)+6%(b)=5000
\n" ); document.write( "6%=.06 read it 6 hundredths
\n" ); document.write( "7%=.07 read it 7 hundredths
\n" ); document.write( ".07a+.06b=5000
\n" ); document.write( "substitute (80000-a) for b in the equation above and solve.
\n" ); document.write( "BTW The woman is named John?
\n" ); document.write( "John is referred to as her and she.
