Let $\"+n+\"$ = the number
\n" ); document.write( "the number increased by 12% is:
\n" ); document.write( " $\"+n+%2B+.12n+\"$
\n" ); document.write( "Now this number decreased by 12% is:
\n" ); document.write( " $\"+n+%2B+.12n+-+.12%2A%28+n+%2B+.12n+%29+\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"+n+%2B+.12n+-+.12%2A%28+n+%2B+.12n+%29+=+86.7328+\"$
\n" ); document.write( " $\"+n+%2B+.12n+-+.12n+-+.0144n+=+86.7328+\"$
\n" ); document.write( " $\"+n+-+.0144n+=+86.7328+\"$
