one Math problem confused by新东方
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%. What was the total rent the motel actually charged for that night
NOS's answer is 600
But I think it should be 800
