Answer:
To determine which cream cheese is a better buy, we need to compare the price per unit of volume for each brand.
For Brand Y cream cheese:
Price per unit = 44 AED / 220 ml = 0.2 AED/ml
For Brand Z cream cheese:
Price per unit = 100 AED / 470 ml = 0.2127 AED/ml
Since the price per unit of volume for Brand Y cream cheese is 0.2 AED/ml and the price per unit of volume for Brand Z cream cheese is 0.2127 AED/ml, Brand Y cream cheese is cheaper per unit of volume. Therefore, Brand Y cream cheese is a better buy.
