the best buy, is the 4- kilogram bag of lollipops for $18.40.
step-by-step explanation:
i found my answer by dividing the cost of each bag by their respective weights.
14.88 divided by 2 = 7.44
17.29 divided by 3 = 5.77
18.4 divided by 4 = 4.6
24.4 divided by 5 = 4.88
by this, i found that the 4 kilo bag is the best buy.
