The expression that represents the cost of y books is 12y + 3.
Given that,
- The charge for the first copy of the book is $15.
- For each extra copy, the charge is $12.
- Here we assume the number of books be y.
Now based on the above information, the expression should be
= 12y + (15 - 12)
= 12y + 3
Therefore we can conclude that option F is correct.

you can never escape it tbh lol
