Eight 3 pens and 5 pencils were sold in a pack at a bookstore. How many pens and pencils did Tom buy in total if he bought 4 packs

Answer 1

(3+5) * 4 = ?

Answer 2

I’m gonna say that is 8 pens if not 83 or 3.
You can do the following since I’m not providing answers:
83+5x4
8+5x4
3+5x4
Not sure of any other combo since I can’t figure out any others.
