Complementary:
An example of complementary demand in my life is buying noodles and spaghetti sauce. If I were to go to the store to buy things for dinner and I bought a jar of spaghetti sauce, then I would also buy noodles. This is complementary demand because the two products are often bought together. Their individual demands are linked together.
Substitue:
An example of substitute demand in my life is dog food. My dog is not a very picky eater. He will eat about anything we give to him. We try to buy healthy dog food, but if the kind we like becomes to expensive then we will purchase a cheaper kind to feed him. This is an example of substitute demand because when we don't want to buy an expensive product, we replace it with a similar but cheaper product.
Inelastic:
An example of inelastic demand in my life is water. I (or rather, my family) is going to pay for clean and safe water to be pumped to our house at almost any price. There is no substitute for clean and safe water in your own house. This is an example of inelastic demand because we are willing to pay as much or as little as we have to, and the amount we demand of it will hardly change.
Elastic:
An example of elastic demand in my life is CDs. When I go to the store and albums from bands I like are only $5, I will buy a few of the albums. If they are $10 I will probably buy one, maybe two. If they are $15 I probably won't buy any. This is an example of elastic demand in my life because as the price of the CDs get higher I buy less, and as the price gets lower I buy more.
