Find xy/x

(1) xy - (x-1)y = x-1

y = x -1

(2) xy - (xy/2) = 7x/2

y = 7

IMO

Total Campers = x
Food cost per camper = y
Total food expenses = xy

Percent of the total food expenses that each camper have to pay = $$\frac{y}{xy}$$ ==> $$\frac{1}{x}$$

Thus, to answer the question, we need to find the value of x.

Stmt 1: $$xy = (x-1)(y-1)$$ - Not sufficient
Stmt 2: $$xy = \frac{x}{2}(y+7)$$ ==> $$y=7$$- Not Sufficient (we need value of x)

With Stmt 1 & 2 combined, we can find the value of x.

Hence C
