Answer:
D) 10.00 for a 36 pack
Step-by-step explanation:
(I'm going up by the smallest pack to the highest because I noticed they are all multiples of 6)
1.80 for a 6 pack (double it to become a 12 pack)
3.60 for a 12 pack but the other 12 pack is more expensive making a 6 pack cheaper. (add another 6 pack)
5.40 for a 18 pack (add another 6pack)
7.20 for a 24 pack so this means the 6pack is more expensive and a 24pack is cheaper (in gonna keep adding till we get to 36 pack)
9 for a 30 pack
10.80 for a 36 pack
