Answer 1

Some of the numbers are missing from your message (the counts in the survey and the total number of marathon participants). I can’t compute the answer until I have those.

How to get the answer once you have the data:
1. Let W, S, F be the numbers from the survey for Water, Sports Drink and Fruit Juice. Let T = W + S + F (the survey total).
2. Let N be the number of runners participating in the marathon.
3. Estimated number who want a sports drink ≈ (S / T) × N. Round to the nearest whole runner and pick the closest answer choice.

Example: if the survey had W = 300, S = 200, F = 500 (so T = 1000) and N = 4000 runners, then estimated sports-drink drinkers = (200/1000)×4000 = 0.2×4000 = 800.

Send the survey counts and the marathon total and I’ll compute the exact answer and pick the correct choice.
