题目是: 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.
答案是B,我选的E
是因为选项2,如果sales of 350,000 units的profit大于5million, 那么sales of 380,000 units的profit一定更大于5 million,从而大于4 million么?我有点儿混乱。。。 |
