I have math question, I'm trying to get better at it

No it's not for school work but I'm looking at bulk items on Amazon, I want to know and learn how to get the uni price.
I used to be good in math but it's been awhile.
For example, there's these fidget popper keychains I am looking at.
If there's 80 pieces of the fidget toys and the whole thing costs $11.99, what would the unit price be?
This might be simple math but I just want to learn it again.
