1. Since we dont know total individual membership we cant determine revenue from family membership from this condition. Insufficient.

2. say x is total no.of individual memberships; and y is total family memberships
from the statement we have y=1.5x
and from the question we have x+y=480000
2 equations and 2 variables are enough to solve teh equations . Solve for y. sufficeint

Re: A swim club that sold only individual and family memberships charged $[#permalink] 1 Kudos The correct answer is C Statement 1. - Let the revenue generated from individuals be i, Therefore that generated from families is f = 480,000 - i The statement says that 480,000 - i = 3i, solving for i we can get the values of i & f. This however does not provide us with the value of the charge for a family membership. Hence insufficient. Statement 2. - This statement too is insufficient as it gives us the numbers of the subscriptions as a proportion and not the exact values. When combined, we can deduce the exact charge for a family membership. Hence C Originally posted by omegacube on 18 Dec 2014, 22:13.

Tough and Tricky questions: Word Problems.

A swim club that sold only individual and family memberships charged $300 for an individual membership. If the club’s total revenue from memberships was$480,000, what was the charge for a family membership ?

(1) The revenue from individual memberships was 1/4 of the total revenue from memberships.
(2) The club sold 1.5 times as many family member- ships as individual memberships.

Kudos for a correct solution.

The answer is C. Solution is in the attached picture
