钱永强数学题答案错了?

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?

同意,他似乎搞混了实际和应当。再怎么说,实际也应该比应当多呀,要不怎么说减少呢?
