I can't figure out the calories in this popcorn.

Question

So I have a Food Club Popcorn, Butter Light that comes in a box with 3 packets. I'm usually good with figuring out how much calories a food has but this one is just confusing the c**p out of me...the nutrition info in the back says:

Serving Size 2 Tbsp (33g) as packaged

Serving Per Carton about 8

Amount per serving:

-Unpopped(140 calories)

-Per cup popped (30 calories)

So if I pop one of the three bags, how many calories would the entire bag be????

Answer 1

measure the cups of popped corn, and multiply it by 30- then you know.
