Q6: Leo can buy a certain computer for p1 dollars in State A, where the sales tax is t1 percent, or he can buy the same computer for p2 dollars in State B, where the sales tax is t2 percent.  Is the total cost of the computer greater in State A than in State B?

(1)    t1 > t2

(2)   p1t1 > p2t

                                                                                                                                   Answer: E

我认为答案是C呀~。。纠结的地方在于。。是否可以根据条件1和2推出：P1>2？？？？

大家帮我解答下。。是不是不等式乘法不能这么简单考虑？

真该打。。。。。咋刚脑子酱紫了~~

直接带个最简单的数字就可以了。~不过还是查了理论。。
