P58 Tokens are sold in packs of 40 for $4.00 意思是团购的话每个token 0.1 $ ,前面说The toll for a certain bridge is $0.15 or 1 token.意思是单买的话每个token 0.15 $ ,所以买40个token剩下的钱的百分比是 (4...by 3 inches on all sides和by 2 inches on al sides指的是tablecloth还是square tabletop 啊？当然是桌布，这句子不难啊怎么看不懂。理解不了就按计算器吧。看来你基础知识很不扎实，数学和英语都是。既然形容的是桌布，那桌布面积怎么不知道啊那我问你，桌子面积是多少？两个桌子一样吗？
