on a saturday night,each of the rooms at a certainmotel was remted for either $60 or $40,if 10 of the room sthat were rented for $60 had instead been rented for $40 ,then the total rent the motal charged for that night would have been reduced by 25%,what was the total rent the mtal actually charged for that night?
my answer: (60-40)*/0.25=800 but qian's answer is 800-200=600. what do you think?
