A certain group of car dealerships agreed to donate x dollars to a Red Cross chapter for each car sold during a 30-day period. What was the total amount that was expected to be donated?

1) A total of 500 cars were expected to be sold
2) 60 more cars were sold than expected, so that the total amount actually donated was $28,000 Director Joined: 30 Jun 2007 Posts: 793 Followers: 1 Kudos [?]: 116 [0], given: 0 Re: GMAT Prep: Car Dealerships [#permalink] 17 Feb 2008, 18:43 In order to compute the total donation amount, we need two things:1.X and 2.Total number of cars. 1) Total of 500 cars sold. Fine! But, we don’t know x, so donation amount cannot be computed. (Not Sufficient) 2) Let N be total number of cars: (N + 60)X = 28000 Again we don’t have N and X – Not Sufficient Combine 1) and 2) 560 * X = 28000 X = 2800 / 56 = 50 Total Contribution = 25000.

What was the total amount that was expected to be donated? y: number cars expected x: donated dollars per car z: actual number of cars sold Want: xy = ? 1) A total of 500 cars were expected to be sold ---------------------------------------------- y = 500 insufficient 2) 60 more cars were sold than expected, so that the total amount actually donated was$28,000
--------------------------------------------------------------------------------------------------
z = 60 + y
xz = 28,000
x(60+y) = 28,000

insufficient
