題目問 total cost

在state A 和 state B買的cost 分別是 p[sub]1[/sub]+p[sub]1[/sub]t[sub]1[/sub] 和p[sub]2[/sub]+p[sub]2[/sub]t[sub]2[/sub]
所以光知道p[sub]1[/sub]t[sub]1[/sub] > p[sub]2[/sub]t[sub]2[/sub]是無法得出答案的
還必須知道p[sub]1[/sub] 和 p[sub]2[/sub]才行

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 > p2t2
這樣吧, 怎都是亂碼?
