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):
[tex]\frac{9}{2}=4.5[/tex] per pack
[tex]\frac{4.5}{24}=0.1875[/tex] or approx 19 cents per can.
At super save store, we have :
12 packs (4 for 10):
[tex]\frac{10}{4}=2.5[/tex] per pack
[tex]\frac{2.5}{12}=0.208[/tex] or approx 21 cents per can.
At price busters store, we have:
12 packs (3 for 9):
[tex]\frac{9}{3}=3[/tex] per pack
[tex]\frac{3}{12}=0.25[/tex] 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.
