Final answer:

The answer explains how to determine the cost of 150g of cheese at a given price per kilo and clarifies the concept of direct proportionality in this scenario.


Explanation:

Direct proportionality: The price of blue cheese is 23.35€ per kilogram. To find the cost of 150 grams of cheese, divide the price by 1000 (to convert grams to kilograms) and then multiply by 150. Therefore, the cost for 150g of cheese is 3.5025€.

Examples: Imagine a pizza weighing 1kg with a price tag of 23.35€. It would cost 6.5025€ to purchase a quarter of that pizza, equivalent to 250g.

Inverse proportionality: If the price of cheese increased, but the quantity available decreased, that would be an inverse proportion. However, in this case, it's direct proportionality as the cost is directly proportional to the weight purchased.
