	For subtractive or negative numbers use a minus sign.
	$
(b)	Use a data table to vary demand from 1000 to 6000 increments of 200 to test the sensitivity of profit to demand. Breakeven occurs where profit goes from a negative to a positive value, that is, breakeven is where total revenue = total cost yielding a profit of zero. In which interval of demand does breakeven occur?
	(i) Breakeven appears in the interval of 3,200 to 3,400 copies.
	(ii) Breakeven appears in the interval of 3,600 to 3,800 copies.
	(iii) Breakeven appears in the interval of 3,800 to 4,000 copies.
	(iv) Breakeven appears in the interval of 4,000 to 4,200 copies.
(c)	Use Goal Seek to answer the following question. With a demand of 3,600 copies, what is the access price per copy that the publisher must charge to break even?
