※ 引述《rnrn ()》之铭言：
: The cost of a square slab is proportional to its thickness and also
: proportional to the square of its length. What is the cost of a square slab
: that is 3 meters long and 0.1 meter thick?
正方形木板的价钱是跟他的厚度成比例的,也跟他的长度成比例.
问一个长3公尺.厚0.1公尺的多少钱
: (1) The cost of a square slab that is 2 meters long and 0.2 meter thick is
: $160 more than the cost of a square slab that is 2 meters long and 0.1 meter
: thick.
一个2公尺长,0.2公尺厚的木板比一个2公尺长,0.1公尺厚的木板多160块
: (2) The cost of a square slab that is 3 meters long and 0.1 meter thick is
: $200 more than the cost of a square slab that is 2 meters long and 0.1 meter
: thick.
一个3公尺长,0.1公尺厚的木板比一个2公尺长,0.1公尺厚的木板多200块
: 嗯! 其实我是看不太懂题目的意思
: 请大家帮我解答 谢谢^^
答案是C吗? 要两个选项才能知道价钱跟长,厚的比率各是多少
应该是这样吧 希望有回答到你的问题~~~

1F：推 GODDAMN:我觉得是E，因为两个条件给的都是how much more.. 10/19 15:32
2F：→ GODDAMN:还是算不出来答案要的是多少钱吧? 10/19 15:33
3F：→ min2:我觉得你说的是对的...我忽略了基本的价钱了... 10/19 16:43
4F：推 jjhgfr:应该是跟长度的平方成正比吧... 10/19 19:11
5F：→ jjhgfr:also proportional to the square of its length 10/19 19:14
