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 380,000 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.
请问为什么B可以呢？ 我理解题目说profit和sales上涨不成比例关系，所以有可能B选项里 sales超过350000之后，利润下降。这样理解有什么问题吗？谢谢
