關於英文的less & more的用法

問題1:

Each person attending a fund-raising party for a certain club was charged the same admission fee. How many people attended the party?

(1) If the admission fee had been $0.75 less and 100 more people had attended, the club would have received the same amount in admission fees.

(2) If the admission fee had been $1.50 more and 100 fewer people had attended, the club would have received the same amount in admission fees.

我真的不知道如何算耶???我是不是有理解錯呀???

(1) admission fee 比0.75低,人數大於100

(2)admission fee 比1.50高,人數低於 100

(1)+(2)合併可以算出來,唉~~我真的不懂~~

請高手幫忙

    Let f = admission fee, p = number of people

    f*p = (f-0.75)*(p+100) ...

    f*p = (f+1.5)*(p-100) ...

    => p = 300 and f = 3

    So, the number of attendance is p=300

    意思就是:

    (1) 若費用便宜個$0.75 但有多100個人入場

    那麼總收入會跟原本是一樣的

    (2) 若費用貴個$1.50 但 入場人數少了100人

    那麼總收入也會和原本一樣
