You can put this solution on YOUR website!
They are producing sofas at a certain rate,
\n" ); document.write( "and rate is the slope, $\"+m+\"$ in a linear equation
\n" ); document.write( " $\"+m+=+245+\"$ sofas/day
\n" ); document.write( "----------------------------
\n" ); document.write( " $\"+1235+\"$ sofas is a constant number of sofas you
\n" ); document.write( "start off with, but if you want to begin at day one,
\n" ); document.write( "subtract out $\"+245%2A3+=+735+\"$ sofas
\n" ); document.write( " $\"+1235+-+735+=+500+\"$ is the constant term, $\"+b+\"$
\n" ); document.write( "-------------------------------------------------
\n" ); document.write( "Now let $\"+t+\"$ = time in days to make $\"+N+\"$ sofas
\n" ); document.write( "The equation would be:
\n" ); document.write( " $\"+N%28t%29+=+245t+%2B+500+\"$
\n" ); document.write( "You are given $\"+N%28t%29+=+5400+\"$
\n" ); document.write( " $\"+5400+=+245t+%2B+500+\"$
\n" ); document.write( " $\"+245t+=+4900+\"$
\n" ); document.write( " $\"+t+=+20+\"$
\n" ); document.write( "20 days are needed to make 5400 sofas
\n" ); document.write( "( with the 3 days included, which I think they want )
\n" ); document.write( "Feel free to get another opinion, too
