Hotel market always has fixed price,and the managers do not normally look at the margin.For example,if a standard room costs £100 a day,the manager will make sure it does not sell for less than that amount.However,if we think out of the box,say,a hotel has three rooms available until 11:50pm,and a customer is willing to pay £80 a day,the manager should consider selling to the customer at least to make a profit,albeit a small one.The marginal benefit is £80,and the marginal cost is only a fraction of it - water and electricity fees.

Hotel market always has fixed price, and also the manager do not think at margin. (这里，do not 应该用does not；think at 应该用think about)More specifically, a standard room cost 100￡ a day, and the manager command that do not sell less then 100￡. (这里cost 应该用单数；command也要用单数；then应该是than；sell后面加if较好）Image that the hotel still has three room available until 11,50pm,（room应该是rooms） and a customer only want to live one day and is willing to pay 80￡a day.（这里，only live加上want to表示打算；willing不是动词，所以要加上is） The manager should consent in order to make profit. Because the marginal benefit is 80￡, and the marginal cost is only a little water and electricity fees.（这里consent后面要加宾语it；另外the没必要，litter改成little）
