I bought some inventory on eBay out of Canada and paid in CAD money. How is that converted to US dollars?

So I spent "C $60.12" Total Canadian dollars I think.

Breakdown was

C 40.00

C 18.00

C  2.12

---

C 60.12

 

Also this inventory is for my 2020 taxes and the purchase was made on 06-30-2020

 

How does that break down?

 

TIA
