Answer:
30 apples
Explanation:
The opportunity cost is the value of the item forgone on the scale of preference due to limited resources available to satisfy our unlimited wants.
If in one hour, Jason can pick 30 apples or one pound of cherries. In one hour, Jose can pick 20 apples or one pound of cherries, then the opportunity cost is the higher number of apples that could have been picked in place of a pound of cherries. This is 30 apples.
