When the government imposes an import quota of 8 million units, this means that the country can only import up to 8 million units of the good, which is a decrease from the previous import quantity of 10 million units.
As a result of this reduced supply (due to the quota), the following is likely to occur:
- The quantity imported will decrease (from 10 million to 8 million).
- The reduced availability of the good is likely to lead to an increase in its per-unit price, as demand remains the same but supply is constrained.
Therefore, the correct response is:
The quantity imported will decrease, and the per-unit price will increase.
