Candy Bar Pricing and Integer Concepts

The video tutorial presents a word problem involving a student with 400 candy bars, each costing 50 cents. It introduces the function P(B), where P represents the price in dollars and B the number of candy bars. The tutorial explains the concept of domain, emphasizing that candy bars must be sold as whole units, thus making the domain an integer. It further defines the interval for the domain, stating that the student can sell between 0 and 400 candy bars, as they cannot exceed their stock.
