✔ 最佳答案
1A) 售價= $320*(100%-30%)
= $320*(70%)
= $320*0.7
= $224
1B) 折扣
=$320-$224
=$96
成本*48%=折扣
成本
=折扣/48%
=$96/0.48
=$200
盈利百份率
=(盈利/成本)*100%
=[($224-$200)/$200]*100%
=(24/200)*100%
=12%

a)=320(1-30%)
=320x0.7
=$224.現在售價是$224.
b)320-224x100%/48%
=200.盈利百份率是+200%.
=320x0.7
=$224.現在售價是$224.
b)320-224x100%/48%
=200.盈利百份率是+200%.

b: (320-224) / 48%

=224
b: (320-224) / 48%
