Answer:
Let the lemonades be represented by = h
Let the hot dog be represented by = 86-h
You can check this by : h+(86-h)=86. (option B)
If a snack cart sells lemonade for $2, it makes $2h for h sold lemonade;
And the cart sells hot dogs for $5, the person makes $5(86-h) for (86-h) sold hot dogs.
In total the vendor gets $330, then equation becomes: 2h+5(86-h)=330.
