Answer:
Mié, Pillar and David should buy the lemonades from shop smart store.
Step-by-step explanation:
At shop smart store, we have:
24 packs (2 for 9):
per pack
or approx 19 cents per can.
At super save store, we have :
12 packs (4 for 10):
per pack
or approx 21 cents per can.
At price busters store, we have:
12 packs (3 for 9):
per pack
equals 25 cents per can.
Now, comparing the three values, we can see that 19 cents per can is the cheapest.
So, Mié, Pillar and David should buy the lemonades from shop smart store.
