问题描述：
A.sent his chauffeur with a note to B.offering to sell B his car for £500.00,and asking B to give his reply to the chauffeur.Being undecided,B gave the chauffeur no reply,but half an hour later posted a letter accepting A’s offer,to A.Has a valid contract come into existence?
答
这段话直译为：
A 派了他的私人司机带上一封文件去找B,提出以500英磅的的价钱把车卖给B,并要求B直接告诉他的司机其答复.由于没有决定好,B没有答复A的私人司机.但是半个小时以后,B给A寄了一封信告诉A他接受A提出的价钱.对于A来说,是不是形成了一个有效的契约约定?
这个问题应该说这个契约是有效的,因为B是发给了A一份书面的回复.post a letter是指寄了一封信,书面的形式的答复是具有证明效力的.所以这份约定是有效的.
