✔ 最佳答案
100% 的 5 份 1 就 等如 20%
將 $125 除 5 就等如 $25
所以 $125 的 20% DISCOUNT 就等如
$125 減 $ 25 答案 : $ 100

算式
將 $125 (100%) 除 5 就 = $25(20%)
將 $125 (100%) 減去 $25(20%) = $ 100 (80%)

discount amount = marked price * discount
= 125 * 20%
= 25 = the money she have saved
so she saved $25
參考: 自己既計算

$125-($125*20%)
=$125-$25
=$100

125-125x(100%-20%)
=125-125x80%
=125-125x0.8
=125-100
=$25
She saved $25.

She save
$125 - $125 * 80% = $25
