On a Saturday night, each of the rooms at a certain motel was rented for either $40 or$60. If 10 of the rooms that were rented for $60 had instead been rented for$40, then the total rent the motel charged for that night would have been reduced by 25 percent. What was the total rent the motel actually charged for that night ?
(A) $600 (B)$800
(C) $1,000 (D)$1,600
(E) $2,400 Senior Manager Joined: 18 Aug 2009 Posts: 328 Followers: 8 Kudos [?]: 297 [0], given: 13 Re: algebra [#permalink] Show Tags 07 Oct 2009, 20:04 Well, if 10 rooms were charged$40 instead of $60, the total rent saved =$200.
Total rent was reduced by 25% = \$200. So Previous rent was 200*4 = 800.
So B.
