Answer: The statement that best describes the relation (package number, price) is: "It is not a function because each package number has two different prices."
In the given table, each package number has a different price for both weekend and weekday packages. For example, package number 1 has a price of $160 for weekends and $110 for weekdays. Similarly, package number 2 has a price of $180 for weekends and $130 for weekdays.
Since each package number has two different prices associated with it, the relation is not a function.
