Step-by-step explanation:

→ Work out area of circle

π × 10² = 100π = 314.159 (3 decimal places)

→ Divide area of circle by box area

314.159 ÷ 46 = 6.8295

→ Round answer as you can't get a decimal of a box

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.
