Question

Chocolate bar A weighs 80 grams and costs $1.00. Chocolate bar B weighs 85 grams and costs $1.20. Which is the best value and why?​

Answer 1

chocolate bar A is the better value, as it costs less per gram compared to chocolate bar B. Even though chocolate bar B is slightly larger, it costs more overall, which makes it a worse value for the consumer.

Answer 2

To determine the best value between chocolate bar A and B, we need to calculate the cost per gram of each chocolate bar.

For chocolate bar A, the cost per gram is:

$1.00 ÷ 80 grams = $0.0125 per gram

For chocolate bar B, the cost per gram is:

$1.20 ÷ 85 grams = $0.0141 per gram

Therefore, chocolate bar A is the better value as it costs less per gram compared to chocolate bar B. While chocolate bar B may weigh slightly more, its higher cost per gram means that you are paying more for each gram of chocolate compared to chocolate bar A.
