Answer:
The government of Birdonia should do nothing.
Explanation:
Equilibrium sugar price of $100 means that at that price($100), more people are willing to buy sugar. Also more firms are willing to supply the commodity at that price.
Hence since consumers are considered rational, they will want to go for a higher value at minimal cost. Opting for imported sugar at $125 is the least the Birdonian citizen will do.
