D : 800
E : 1000

I am getting $2750 as answer. if car X is 25% cheaper - it's price doesn't become 1/4th -- but rather 3/4th of original price. first equation : $$X+Y = 7250$$ second equation : $$0.75X + 1.20 Y = 6450$$. Solving both for X, Y we have : Y = 6750/3 using first equation and solution of Y to find X - Y ( ANswe r to prompt question of " how much is X costlier than Y) We get $$X - Y = 2750$$ Please let me know what you guy's think. Hope this helped.... _________________ Regards, Gladi “Do. Or do not.

[url=https://gmatclub.com:443/forum/memberlist.php?mode=viewprofile&un=Gladiator59][b]Gladiator59[/b][/url] , I got $2,750 as well. [EDIT] X + Y = 7250 Y = 7250 - X .75X + 1.2Y = 6450 .75X + 1.2(7250 - X) = 6450 .75X + 8700 - 1.2X = 6450 -0.45X = -$2250
X = 5,000
Y = 7250 - 5,000 = 2250
X - Y = (5,000 - 2,250) = $2,750 Answer E [url=https://gmatclub.com:443/forum/memberlist.php?mode=viewprofile&un=prady2231][b]prady2231[/b][/url] , Would you please check the question's wording and/or the answers?

A : 500 B : 800 C : 1000 D : 2750 E : 2250 $$x+y = 7250$$ --> $$y = 7250 -x$$ $$x-0.25x + 1.2y = 6450$$ $$x-0.25x+1.2(7250 -x) = 6450$$ $$x-0.25x+8700-1.2x = 6450$$ $$x-0.25x-1.2x=6450-8700$$ $$-0.45x=-2250$$ $$x = 5000$$ $$7250-5000= 2250$$ so its E looks like the OA was incorrect Bunuel can you pay attention to this discussion shouldn't the correct answer be 2,250 ? niks18 ?:) --== Message from the GMAT Club Team ==-- THERE IS LIKELY A BETTER DISCUSSION OF THIS EXACT QUESTION.
