attended the party?

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.

x- number of ppl
y - fee

x*y=T

1. (x+100)(y-.75)=T
2. (x-100)(Y+1.5)=T

3 equations and 3 variables.
