某年製造一件恤衫的成本與其在下年的對應變化百分率記錄於下表中:
~~~~~~~~~布料~~~鈕扣~~~工資~~~其他~~~
成本-----------$150------$50-------$240-----$60--------
變化百分率-減5%------加8%---加12%---減8%
求製造這件恤衫的成本變化百分率
數學功課 百分率 高分!!!

✔ 最佳答案
原本恤衫成本 = 150+50+240+60 = $500新恤衫成本 = 150*(1-5%) + 50*(1+8%) + 240*(1+12%) + 60*(1-8%)
= 150*0.95 + 50*1.08 + 240*1.12 + 60*0.92
= 142.5 + 54 + 268.8 + 55.2
= 520.5
成本變化 = [(520.5-500)/500]*100%
= 20.5/500 * 100%
= 4.1%

新成本價:
(150 x 95% + 50x108% + 240 x 112% + 60x92%)
= $520.5
變化%
= [520.5 - (150+50+240+60)] / 500x100%
= (520.5-500) / 500 x 100%
= 4.1 %
(150 x 95% + 50x108% + 240 x 112% + 60x92%)
= $520.5
變化%
= [520.5 - (150+50+240+60)] / 500x100%
= (520.5-500) / 500 x 100%
= 4.1 %
