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

Let's say there were N people and they each paid X$. We need to find N.

1. Let's translate the words into algebra:

Original amount received = N*X

New amount received = (N + 100) * (X - 0.75)

We are told these two are equal quantities. Equate them

N*X = (N+100)*(X-0.75)

A glance at this should suffice to say that thought the NX term would cancel out, we cannot find N independent of the value of X.

INSUFFICIENT

2. Similar situation which works out to:

N*X = (N - 100)*(X - 1.5)

INSUFFICIENT (cannot isolate N)

Both 1 and 2

We have two independent simultaneous equations in two variables. Sufficient to find each of N and X

SUFFICIENT

Pick C.

C straight forward, two variables can;t be solved from one equation...
