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 = 7552

這題我選E,想不出選C的理由..麻煩大家了

gross pay = $P
題目問$P - $P*t% - $S =?
(1) p - s = 244
(2) pt = 7552
[條件一]不知t,算不出答案
[條件二]不知S,算不出答案
[合併]P-S-Pt%=244-75.52 => 所以答案是C
