document.write( "Question 285517: Hello! I'd greatly appreciate it if anyone can help me on this deceptively hard (for me, at least) word problem. It is as follows:
\n" ); document.write( "A storeowner's average day sales is $500, realizing a profit of 20% of the selling price. To increase the volume of his sale, he advertised his goods by spending an average of $20 a day for advertising. If his average daily sales rose to $700 with the rate of the profit still remaining the same, how much additional profit did the advertising bring?
\n" ); document.write( "Thank you very much for the time and help! Godspeed! :) \n" ); document.write( "

The wording is what makes it hard. Why cannot Mathematicians consider learning English!
\n" ); document.write( "Initially, the sales are $500 from which there is a profit of $100
\n" ); document.write( "Afterwards there are sales of $700, from which there is a profit of $140.
\n" ); document.write( "Assuming that the advertising is an extra cost of $20, the extra profit is $20 less than the $140 - $100 difference, or $20.
\n" ); document.write( "If however, the rate of profit stays the same, this might be construed to mean that the advertising is now included in the costs of sales and does not have to be considered seperately. In that case the profit increase is $40 per day.
\n" ); document.write( "Either interpretation is possible when the question is written in this way. \n" ); document.write( "
