Answer:

Step-by-step explanation:

I assume that songs are $0.99 each.  Let x represent the number of songs you download.  Then the total cost of downloading x songs would be

C(x) = $5.00 + ($0.99/song)x

and ONLY integers = to or greater than 0 make sense here.  The domain is [0,  100) assuming you cannot buy more than 100 songs.

Personally I'd give the answer as "2, whole numbers more than or equal to zero."  However, IF you don't pay the membership fee until ready to actually order one or more songs, then "2, whole numbers greater than or equal to one" makes sense.  You'd pay $5 plus $0.99 for one song, in that case.

The most appropriate domain to calculate the cost of downloading songs is whole number greater than or equal to one.

What are whole number?

Whole numbers include all natural numbers and 0. They are real numbers that do not include fractions, decimals, and negative integers.

It is most appropriate since numbers of songs downloaded cannot be a negative or part quantity.
