關於英文的less & more的用法
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.
(1) admission fee 比0.75低，人數大於100
(2)admission fee 比1.50高，人數低於 100

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
