A clothes shop owner has found that if he sells a particular dress for a price of $200 each, he can sell 100 such dresses in a month. He also knows that for every$4 that he increases the selling price of the dress by, he will sell two dresses less. If in a particular month he increases the price and sells at $P per dress, what is the total revenue he will get in that month from selling these dresses? (A) P^2 / 2 (B) 200 - P/2 (C) 50P + P^2/2 (D) 150P - P^2/4 (E) 200P - P^2/2 Manager Joined: 07 Mar 2005 Posts: 93 ### Show Tags 04 Jun 2005, 17:21 B pick some random number P.

(A) P^2 / 2
(B) 200 - P/2
(C) 50P + P^2/2
(D) 150P - P^2/4
(E) 200P - P^2/2

(100 - (P-200)/2)P = 200P - P^2/, E

One small problem, $2 means one less dress, what about a dollar increase? sell for$201 and make an extra 100 bucks!
