Understand the Problem: Understand the problem. We need to find the domain of the function F(b), which represents the amount of money Eduardo raises from selling b candy bars. The domain is the set of all possible values of b that Eduardo can sell.Lowest Candy Bars Sold: Determine the lowest number of candy bars Eduardo can sell. The minimum number of candy bars Eduardo can sell is 0, as he might not sell any candy bars.Highest Candy Bars Sold: Determine the highest number of candy bars Eduardo can sell. The maximum number of candy bars Eduardo can sell is the total number of candy bars he has, which is 80.Type of Numbers: Determine the type of numbers that represent the number of candy bars sold. Since Eduardo cannot sell a fraction of a candy bar, the number of candy bars sold must be a whole number.Combine Information: Combine the information to find the domain. The domain of F(b) is all whole numbers from 0 to 80, as Eduardo can sell anywhere from 0 to 80 candy bars, inclusive.
