200,000 units.
(2) The pro�t exceeded $5 million on sales of
350,000 units.

IMO B.

STMT 1: Since the stem says that the profit does not increase proportionally, we cannot determine if it would be greater than 4mn for 380,000 units

STMT 2: This tells us that the profit already exceeds 5mn on sales of 350,000 units. Since the stem says that the profit only 'increases', we can be certain that the profit would be greater than 4mn on sales of 380,000 units.
