Answer:
Measure of Value
Step-by-step explanation:
The function of money being illustrated is known as a Measure of Value. This is basically when an item's monetary values are compared when making a trade. In this scenario, both the apples and pineapples are being compared based on their monetary value. Since a single pineapple is worth twice the amount of money that a single apple is worth. Then that means that a fair trade would be two apples for every pineapple which would be a trade of the same amount of monetary value.
