✔ 最佳答案
標價為 120 , 若以6折出售,,那就是120x0.6=72
其盈利百分率為20%,那就是
72x0.2=14.4
玩具的成本也就是
72-14.4=57.6

設該玩具的成本是y
120%y=120x60%
y=60
120%y=120x60%
y=60

Seems to be the solution.
The marked price in 60%:120‧60%
=72
Let x be the prime cost.
x(1+20%)=72
x=60
The marked price in 60%:120‧60%
=72
Let x be the prime cost.
x(1+20%)=72
x=60
