suppose we all agree the following:
1. x, y, z are all positive, i.e., x, y, z >0. Each medal carries some
weight.
2. A gold medal worth at least one silver and one bronze, i.e., x ≥ y + z.
3. Two gold medals worth at least three silver medals, i.e., 2x ≥ 3y.
Note
a. USA media weight ranking (x, y, z) = (1, 1, 1) clearly does not satisfy
the above conditions as it treats gold the same as silver or bronze. Gold
medal only, | l*****g

发帖数: 714 | 3 The problem is, some people don't agree that x ≥ y + z, 2x ≥ 3y. Also
shall we place some weights for 4th, 5th...? Since the whole world uses gold
medal rank except US, it shows most people care about gold way more than
silver or bronze. | r**e

It's a small typo.
= (51x + 21y + 28z) – (36x + 68y + 36z)
= 15x – 18y – 8z
~~should be 17
I want forward to my mailbox, can you help me to fix it first?

就金牌而言，一块足球金牌＝一块举重金牌？？
how about 一块足球金牌＝10块举重
一块篮球金牌＝5块单人跳水金牌
中国是本届奥运金牌第一国，这可以了。但是还没有强大到各方面都能胜出的地步，比
如三大球（足球排球篮球，美国拿了四枚金牌，一枚银牌，中国呢？），国内新浪网有
网友说宁愿用12枚举重金牌去换一枚三大球的金牌，就是反映了一种声音。
拜托，别比了。金牌榜第一已经够好了！！ |
