Answer:
After the imposition of the subsidy, 240,000 bushels of wheat would be sold in the market.
Step-by-step explanation:
When we talk about unit elastic we mean that the exact same porcentage in quantity demanded is exactly the same porcentage in price reduction.
So if the price of a bushel of weath is reduced 20% ((2.5-2)/2.5) the demand of bushels of wheat will rise in the exact 20% so 200,000*1.2=240,000
