5个苹果和3个香蕉花费2.47美元,如果苹果和香蕉的价格换一下,同样数目的水果将会花费3.13美元,请问,6个苹果和6个香蕉要花多少钱?
5个苹果和3个香蕉=2.47
5个香蕉和3个苹果=3.13
相加,8个苹果和8个香蕉=5.6,所以,1个苹果和1个香蕉=0.7
6个苹果和6个香蕉=4.2美元
Suppose the price of an apple is X and that of a banana is Y.
Then we got 5X+3Y=2.47 and 5Y+3X=3.13
So that X+Y=0.7
Finally,6X+6Y=4.2
5苹果+3香蕉=2.47美元 现在苹果和香蕉的价格对换,买同样数量的水果即
5苹果+3香蕉=3.13美元 问你6苹果+6香蕉需要多少钱?
5X+3Y=2.47
5Y+3X=3.13
X=0.185美元
Y=0.515美元
自己翻译吧。
5苹果和3香蕉花费 $2.47,如果苹果和香蕉的价格交换(exchanged是交换的意思),同样数量的水果花费$3.13,那么6个苹果和6个香蕉要花费多少?
设苹果价格M每个,香蕉N每个,则
5M+3N=2.47 a
5N+3M=3.13 b
所以式a+b得到 8M+8N=5.6
所以M+N=0.7
则 6M+6N=$4.2...
