the profit from the sale of a certain appliance increases,销售某东西的利润上升了,though not proportionally,with the number of units sold.尽管和销售数量相比不成比例。 Did the profit exceeded $4 million on sales 380000units? 卖380000单位利润能超过$4 million么 ?
1 the profit exceeded $2 million on sales of 200000units 卖200000单位时,利润超过$2 million 2 the profit exceeded $5 million on sales of 350000 units 卖350000单位时,利润超过$5 million
由题知道,利润增加和销售数量成不成比例的正相关关系!
2 卖 350000时,利润就超过了$5 million ,那么卖380000就肯定超过$4 million了。 |
