To determine the opportunity cost of producing one unit of Good B in terms of Good A, we can use the production possibilities given.
- If the country produces 20,000 units of Good A, it foregoes the production of Good B (5,000 units).
The opportunity cost can be calculated as follows:
- If the country produces 20,000 units of Good A, it can produce 5,000 units of Good B.
- Therefore, producing 5,000 units of Good B would mean giving up 20,000 units of Good A.
To find the opportunity cost of producing one unit of Good B, we can divide the total units of Good A given up (20,000) by the total units of Good B produced (5,000):
\[ \text{Opportunity Cost of 1 unit of Good B} = \frac{20,000 , \text{units of Good A}}{5,000 , \text{units of Good B}} = 4 , \text{units of Good A} \]
Thus, the opportunity cost of producing one unit of Good B is 4 units of Good A.
