不好意思，搞错了。回答下面的另外一个问题把。
City Number Polled Percent of Votes for X Percent of Votes for Y
1/ 1000/ 60 /40（city/number polled/percent of votes for x/percent of votes for y)
2 /1600/ 50 /50
3/ 2000/ 40/ 60
4/ 1800/ 50/ 50
5 /1200/ 30/ 70
The table above shows the results from a recent statewide election in which the candidate with the higher number of votes from the five cities was declared the winner. Which city had the greatest number of votes for the winner?
and why?i need to know the equation.
因为在准备考试，所以想把题目全体复习一下。谢谢了
