Answer:
Different price for a car wash on Tuesday versus Wednesday
Explanation:
Price discrimination is when identical goods are sold at different prices from the same provider. A Ford truck and a Ford car are not identical items. The average price of a home in two very different states (one highly desirable due to temperature/climate, and one less desirable for the same reason) do not constitute price discrimination. But the days of the week someone is able to wash a car, at the same car wash is an identical service at a different price.
