✔ 最佳答案
一步一步黎唔使緊張marked price 70% higher than its cost.
所以marked price=1.7x
sold to a customer at a discount of 5%.
所以selling price=1.7x * (1-0.05)=1.615x
a) percentage gain= (final price-original price)/original price * 100%
=(1.615x-x)/x *100%
=61.5%
b)個客畀左幾左錢=selling price
所以 2907=1.615x
x =1800
記住個係x=1800, 唔係x=$1800
因為條問題個x係唔包括$

a)
Selling Price = X x 1.7 x 0.95
Selling Price = X x 1.615
Therefore the Percentage Gain = 61.5%
b) If Selling Price = 2907, X = 2907/1.615 = 1800.
Selling Price = X x 1.7 x 0.95
Selling Price = X x 1.615
Therefore the Percentage Gain = 61.5%
b) If Selling Price = 2907, X = 2907/1.615 = 1800.
