The question should be more precise. It should say that how many cents does "each" soda costs.

Anyway, here's the solution by plugging in numbers. Suppose, one soda costs $1 (100 cents) so one hot dog costs $2 (200 cents) as the hot dog costs twice as much as soda.

Suppose the vendor sells 10 hot dogs and 10 sodas so in total he makes d = $30.

Now let's try A by plugging h = 10, s = 10, and d = 10. We have (100*30)/(10 + 2(10)) = 100 cents. So A is the answer as each soda costs 100 cents.
