Homework Help: algebra

How do I do this problem:

Chelsea sold baked goods to raise money for various charitable organizations. She gave a third of the money raised to the American Red Cross. Then gave a fourth of that money to United Way. THEN gave half of the money to Twin city Missions. If Twin City Missions received $200, how much money did Chelsea have in the beginning?

Let X = beginning amount

I assume that the first two are proportions of the grand total and the last is a proportion of the remainder.

(X - 1/3 X - 1/4 X)/2 = $200

Solve for X.

I hope this helps. Thanks for asking.
