The profit from the sale of a certain appliance increases, though not proportionally, with the number of units sold. did the profit exceed $4 million on sales of 380000 units? (1) The profit exceeded$2 million on sales of 200,000 units.
(2) The profit exceeded $5 million on sales of 350,000 units. OG12, 23 DS Are we supposed to assume that the remaining 150,000 in A and the remaining 30,000 in B will generate different profits?-that is, they are sold separately as different chunks? Can't we just say, 2 Million / 200,000 = price per unit? Therefore, answer is D. OA is [Reveal] Spoiler: B Some people calculate it profit for A this way [Reveal] Spoiler: So, for 380,000 units, the profit exceeded (380,000 * 2)/200,000 =$3.8 million, but it is not clear if the profit exceeded $4 million or not; NOT sufficient. Where did they get the 2 from?

Two important notes from the stem:
A. The profit from the sale increases with the number of units sold, so the profit on sales of 2 units is more than the profit on sales of 1 unit;
B. That increase is not proportional, so even though the profit on sales of 2 units is more than the profit on sales of 1 unit, it's not twice as much (it can be 1.1 times more, 5 times more, ..., 1,000,000 times more).

(1) The profit exceeded $2 million on sales of 200,000 units --> since the increase is not proportional we can not say whether the profit exceeded$4 million on sales of 380,000 units. Not sufficient.

(2) The profit exceeded $5 million on sales of 350,000 units --> since the profit on sales of 350,000 units, which is less than 380,000 units, is ALREADY greater than$4 million, then the profit on sales of 380,000 units will definitely be greater than \$4 million. Sufficient.

Hope it's clear.
