Answer:
The correct answer is - 40.
Explanation:
In the price ceiling, The government added a price over which companies can not charge for their particular products. In this scenario, the government charges a price ceiling of $4.
Without price ceiling, equilibrium in the market would have occurred at $5 where the amount requested equivalents amount provided (80 units). In any case, since the firm is compelled to charge $4, there will be an abundance of demand in the economy. From the demand and supply plan we can see that at a cost $4 amount requested is 100 units and the amount provided is 40 units. Consequently, at max, 40 units can be traded in the market at value of $4.
Thus, the correct answer is - 40.
