✔ 最佳答案
Let the price of the camera be $yy(1+20%)(1-10%)=y+256
27y/25=y+256
27y=25y+6400
2y=6400
y=3200
Therefore the cost price of the camera is $3200.

Let x be the cost price of the camera
x[(1+20%)(1-10%)-1]=256
x(0.08)=256
x=3200
so, the cost price of the camera is $3200.
x[(1+20%)(1-10%)-1]=256
x(0.08)=256
x=3200
so, the cost price of the camera is $3200.
