Identify whether or not the situations constitute price discrimination and why/why not:

personalized pricing: a large company uses data from consumers including general vicinity of where they live, the type of computer they are using in order to decide prices for the viewer (ex. someone who buys x products tend to spend more than someone who buys y product)

dynamic pricing: electric company serving Central Michigan presents prices in real-time based on supply & demand in wholesale electricity. The company buys the electricity in wholesale for the consumer and charges consumer wholesale price.
