Answer: Terry should buy the half-liter of water that costs $2.11 because buying 200 litres here is cheaper.

Step-by-step explanation:

Terry is buying water and needs 22 liters. A half-liter of water costs $2.11. Using this information, 22 litres will cost:

= 22 : 1/2 * 2.11

= 22 * 2 * 2.11

= $92.84

Also, A 200 - milliliter container of water costs $1.01. Using this information, 22 litres will cost:

= 22 * 1.01 : 200/1000

= 22 * 1.01 * 1000/200

= 22 * 1.01 * 5

= $111.1

Based on this information, Terry should buy the half-liter of water that costs $2.11 because buying 200 litres here is cheaper.
