In order to determine which store offers the best buy for candy, we would determine the cost per pack of candy at each store.
For sweet store,
12 packs cost $3
Thus,
1 pack would cost 3/12 = $0.25
For Delicious Treats,
22 packs cost $4.62
Thus,
1 pack would cost 4.62/22 = $0.21
For Sugar Factory,
18 packs cost $5.4
Thus,
1 pack would cost 5.4/18 = $0.3
For Chocolate Shop,
36 packs cost $7.20
Thus,
1 pack would cost 7.20/36 = $0.2
