Ketchup is a complement (as well as a condiment) for hot dogs. If the price of hot dogs rises, what happens to the market for ketchup? For tomatoes? For tomato juice? For orange juice?

They will decrease except for Orange Juice

Explanation:

When prices for an item increase this causes less people to be able to afford paying for that item. Therefore, demand for that item decreases. Since Ketchup is a complimentary item for hot dogs this would cause demand for Ketchup to decrease as well and the same goes for all the ingredients used to make ketchup. This includes tomatoes and tomato juice, their market would decrease as well. Orange Juice is not directly affected by such an event since it is not complimentary to hot dogs.
