a store is selling cookies for $8.00 for 12 bags. how much will it cost if you want to buy 30 for your class

I actually don't know but I think it's is 11

Ok so first you will need 3 bags since 12*2 is 24 that wont be enough for the whole class so 12*3 = 36 so now that we figured out how many bags we need now we have to multiply $8.00 by three the answer is $24
