✔ 最佳答案
let the original cost is xthen
(621-x)/x=0.08
621-x=0.08x
x=575
the shop owner would like to raise the profit percent to 20%
that means the profit
=0.2*x
=0.2*575
=115
the new selling price of the dress
=x+115
=575+115
=690

Ans：
621/(1+8%)x(1+20%)
=621/1.08x1.2
=575x1.2
=$690
621/(1+8%)x(1+20%)
=621/1.08x1.2
=575x1.2
=$690
