You can put this solution on YOUR website!
looks like the break even point is $4000 in sales in one week as follows:
\n" ); document.write( "200 + (.10)*x = 400 + (.05)*x
\n" ); document.write( ".10*x - .05*x = 400 - 200
\n" ); document.write( ".05*x = 200
\n" ); document.write( "x = 200/.05 = 4000
\n" ); document.write( "they are the same AT this point.
\n" ); document.write( "above this point, then Company A offer should be better.
\n" ); document.write( "to prove, take sales of $5000.
\n" ); document.write( "then .10*5000 + 200 should be greater than .05*5000 + 400.
\n" ); document.write( "calculating out we get
\n" ); document.write( "$500 + 200 = $700 for company A and $250 + $400 = $650 for company B which means company A is better when sales each week are above $4000.
\n" ); document.write( "
\n" ); document.write( "
\n" );
