To determine

In a supply-demand demand diagram, draw the shift of the demand curve for hamburgers in your hometown due to the following events. In each case, show the effect on equilibrium price and quantity.

1. The price of taco increases.
2. All hamburger sellers raise the price of their French fries.
3. Income falls in town. Assume that hamburgers are a normal good for most people.
4. Income falls in town. Assume that hamburgers are an inferior good for most people.
5. Hot dog stands cut the price of hot dogs.

Normal Goods: Normal goods are those goods which have a direct relationship between the income and quantity demanded. When income increases the quantity demanded also increases and vice versa.

Substitute goods: Substitute goods are otherwise known as alternative goods which are used for the same purpose e.g. Tea and Coffee.

Complementary goods: The complementary goods are those goods are used together. For e.g. pen and ink.

Inferior goods: The inferior goods are those kinds of goods it demanded decreases when the income of the people increases for e.g. Potatoes.
