Y is the Audio Book.

"determine the price of one music album and one audio book"

"She lets x represent the cost of one music album."

According to this information "One Audio Book" should be the correct answer. Have a great day!

Answer:

y will represent the cost of one audio book.

Explanation:

Here, the cost of 3 music albums and 5 audio books is $49.60 and 1 music album and 2 audio books is $20.50,

Since, there are two unknown values,

First one is the cost of one music album,

Second one is the cost of one audio book,

We know that, for finding an unknown value we take a variable,

If we have variables x and y in which x represent the cost of one music album, then y must represent the cost of one audio album.
