Let h be the number of lemonade sold. If the vendor sold 86 items today and h of them are lemonade, then the rest are hot dogs, so he sold 86-h hot dogs.

When you add the number of sold lemonade and hot dogs, then you get 86 items in total:

h+(86-h)=86.

This equation is exactly the same as equation

(86-h)+h=86.

Moreover,

1. if a snack cart sells lemonade for $2, then he gets $2h for h sold lemonade;

2. if a snack cart sells hot dogs for $5, then he gets $5(86-h) for (86-h) sold hot dogs.

In total he gets $330, then

2h+5(86-h)=330.

Both these equations are true, but only first is among given options.

Answer: correct choice is B.
