17 Chris 是X，Pat就是 5X。5X + X = 48 ，X = 8 = Chris
10 9500 - 6500 = 3000 利润。3000/50 = 60 个轮胎
27 前提：Jose电话Victor。Victor电话Beth。
推论：Jose没有电话Beth。这个推论不确定，前提给的条件不够。

Answer 3

1.charis买的看做x，则总共就是6x个苹果，6x=48.x=8.所以none of these
2.总共赚的钱9500-6500=3000，每件赚了50。一共3000/50=60
3......应该是uncertain吧。呵呵，我理解是打电话的意思。这个我不懂了。。

Answer 4

17. Chris buy 8 .So the answer is none of these
10.60. (9,500-6,500)÷50＝60
27.uncertain。因为Jose不一定有打电话给Beth.
