哥哥比弟弟:
500x40%=200
哥哥比妹妹:
500x25%=125
弟弟比妹妹:
200x25%=50
妹妹最後得到:
125+50=175
弟弟最後餘下:
200-50=150
總式：
a)500x15%+500x40%x25%
=500x15/100+500x40/100x25/100
=75+100
=175
b)500x40%x(1-25%)
=500x40/100x75/100
=200x75/100

firstly
$500 X 40% -->弟弟= $200
$500 X 15% -->妹妹= $75
secondly
弟弟把$200 --> $200 X 25%妹妹也就是$50
lastly
弟弟有$200-$50=$150
妹妹有$75+$50=$125
$500 X 40% -->弟弟= $200
$500 X 15% -->妹妹= $75
secondly
弟弟把$200 --> $200 X 25%妹妹也就是$50
lastly
弟弟有$200-$50=$150
妹妹有$75+$50=$125

首先我地先計左弟弟先
弟弟最後餘下:
500×40%×(1-25%)
=200×75%
=$150
然後再計妹妹
妹妹最後得到:
500×15%+150×25%
=75+37.5
=$112.5
弟弟最後餘下:
500×40%×(1-25%)
=200×75%
=$150
然後再計妹妹
妹妹最後得到:
500×15%+150×25%
=75+37.5
=$112.5
