Explanation:
In Economics, there are primarily two (2) factors which affect the availability and the price at which goods and services are sold or provided, these are demand and supply.
The law of demand states that, the higher the demand for goods and services, the higher the price it would be sold all things being equal. On the other hand, law of supply states that the higher the price of goods and services, the lower the supply.
Generally, consumers would like to be buy a product as its price falls or become inexpensive.
For substitute or complement products (goods), the price elasticity of demand is always positive because the demand of a product increases when the price of its close substitute (alternative) increases.
In this scenario, Ketchup is a complement (as well as a condiment) for hot dogs. If the price of hot dogs rises, the quantity of hot dogs demanded falls, which lowers the demand for ketchup. Because of the change in the equilibrium quantity of ketchup, the demand for tomatoes by ketchup producers falls, causing the equilibrium price of tomatoes to decrease. This means producers of tomato juice face lower input prices, and the supply curve for tomato juice increases. The resulting fall in the price of tomato juice causes people to substitute away from orange juice and toward tomato juice, so the demand for orange juice falls.
