(1) First: Calculate Cash Discount = $395 - $209 = $186
Second: Divide Cash Discount to 原價 = $186 / $395 = 0.471 = 47.1% off the 原價
Third: 1 - 0.471 = 0.529 = 52.9% of the 原價
In summary: the equation (列式) is 1-((395-209)/395)=0.529 -> 0.529x100% = 52.9%
(2) First: Calculate Cash Discount = $44 - $36.9 = $7.1
Second: Divide Cash Discount to 原價 = $7.1 / $44 = 0.161 = 16.1% off the 原價
Third: 1 - 0.161 = 0.839 = 83.9% of the 原價
In summary: the equation (列式) is 1-((44-36.9)/44)=0.839 -> 0.839x100% = 83.9%
Second: Divide Cash Discount to 原價 = $186 / $395 = 0.471 = 47.1% off the 原價
Third: 1 - 0.471 = 0.529 = 52.9% of the 原價
In summary: the equation (列式) is 1-((395-209)/395)=0.529 -> 0.529x100% = 52.9%
(2) First: Calculate Cash Discount = $44 - $36.9 = $7.1
Second: Divide Cash Discount to 原價 = $7.1 / $44 = 0.161 = 16.1% off the 原價
Third: 1 - 0.161 = 0.839 = 83.9% of the 原價
In summary: the equation (列式) is 1-((44-36.9)/44)=0.839 -> 0.839x100% = 83.9%

(1) $209/$395 = 0.52911 = 52.911%
(2) $36.90/$44.00 = 0.838636 = 83.8636%
兩個的折扣均不是完整的百分比，只可以四捨五入取近似值
(1)的折扣是大約五二折，英文為47.099%off
(2)的折扣大約為八三折，英文為16.1364%off
