✔ 最佳答案
The man buys the football by 60% off , i.e.= $175 x 40%
= $70
and he resells it at its marked price, the profit he gains
= (new value - old value)/old value x 100%
175 - 70
= -------------- x 100%
70
= 105/70 x 100%
= 150%
參考: always remember (new-old)/old x 100%

買既價錢
$175*60%=$70
所賺的錢
$175-$70=$105
profit%
70分之105,再乘100%
答案=150%
