There is 20 cigarettes in a pack
If you where to have 500 that would mean you need 25 packs
Cigarette prices in America vary from $6.11 to 11.50
The midpoint of 6 and 11 is 8.5
8.5 × 25=212.5
So if you where to do this it would be roughly 212.05 USD

I want to know what happens if you light a firestarter on that
