这一题应该是p-pt-s吗？为什麽答案是a?可不可以有哪位可以给在下解释一下。

Q12:

From Leland’s gross pay of p dollars last week, t percent was deducted for taxes and then s dollars was deducted for savings.  What amount of Leland’s gross pay last week remained after these two deductions?

(1)     p - s = 244

(2)     pt = 7,552

then s dollars was deducted for savings. 

这句话已经说了税扣掉多少钱了。

所以剩下就是p－s了。

gross pay:p (应该是指税前收入吧)

tax:t

save:s

那么剩下的为p(1-t)-s=p-s-pt

选C

不过似乎题目中的(p-s)的值小了点.
