Answer:
2A; 1/2A
Step-by-step explanation:
Opportunity cost or implicit is the cost of the option forgone when one alternative is chosen over other alternatives.
To determine opportunity cost, add the total amount of good A and B produced by each country
Total quantity of good A produced by country 1 = 300
Total quantity of good b produced by country 1 = 150
opportunity cost of producing good B = 300A/ 150 = 2A
Total quantity of good A produced by country 2 = 225
Total quantity of good b produced by country 2 = 450
opportunity cost of producing good B = 225 / 450 = 0.5A
