George is trying to make some decisions about his business and has come up with p = (x - 100)(x + 20), where p represents his profit margin and x represents the number of dvds he sold. what does (x - 100) mean? a) that he will make $100 if he sells no dvds b) that the most amount of money he can make is $100. eliminate c) that in order to make zero profit he must sell 100 dvds. d) that in order to make the most profit he must sell 100 dvds.

C) That in order to make zero profit he must sell 100 DVDs.

Step-by-step explanation:

George has calculated profit funcion of his business as

where x represents the number of DVDs he sold.

From this expression we find that profit is 0 when

Option a is wrong because if x=0, loss =2000.  B is wrong because he does not get any profit for sales of 100.

D is wrong because 0 is not maximum profit.

Hence from the four options given we find that option C is right answer.

C) That in order to make zero profit he must sell 100 DVDs.
