Answer:
Dane is better off buying the half liter of water for $1.21
Explanation:
1/2 liter = $2.38
250 millilitre = $1.21
250 mm = 0.25 liter
$1.21 + $1.21 = $2.42 + $2.42 = $4.84
One liter from the 250 mm deal will equal $4.84.
So 4 liters from the 250 mm deal will equal $19.36.
$2.38 + $2.38 = $4.76
One liter from the half liter deal will equal $4.76.
So 4 liters from the half liter deal will equal $19.04.
