What is a key factor to consider when comparing prices of different products?

Answer Details

When comparing prices of different products, the most reliable factor to consider is the unit price - the cost per standard unit of measurement (per kilogram, per litre, per item, etc.). The unit price allows a consumer to make a fair, objective comparison between products that may come in different package sizes, brands, or formats.

For example, a 500g bag of rice priced at 800 naira and a 2kg bag priced at 2,800 naira cannot be compared directly by their total price. Calculating the unit price reveals that the 500g bag costs 1,600 naira per kg while the 2kg bag costs 1,400 naira per kg, making the larger bag better value per unit.

The other options are unreliable bases for price comparison. A brand name does not guarantee better value - premium brands may charge higher prices for equivalent quality. Advertising claims are designed to persuade, not to provide objective cost comparisons. Packaging design appeals to visual preference and does not reflect the actual value of the product inside.

Exam tip: In consumer education, always distinguish between total price (what you pay at the counter) and unit price (what you pay per standard measure). Unit price is the tool that enables genuine value comparison across products of different sizes and brands.
