Effects of Change on Demand

There is multiple reasons for the demand for products or services to change. To begin with there is individual reasons such as your preference or income. After that the prices of related products/services, expectations for the future, or population changes.

When it comes to me, I have a demand for going out and having a quality meal somewhere. This demand is affected personally by; my income, available time and if I have a desire for certain food. Outside things that affect my demand are; limited seating at restaurants and the quality of food available.

Here is a chart that shows a possible demand for me to go out for dinner over a 2 week period, and how it relates to the going price of a single entree.
