Given that the value of camera equipment depreciates at the constant rate .
Since the depreciation amount is constant every year ,let us assume the depreciation amount to be x .
After 12 years ,the value of camera equipment becomes zero .
So we can write the following ;
32400-12x=0
12x=32400
[tex]x=\frac{32400}{12}=2700[/tex]
Now this means that the value of camera equipment depreciates by 2700 per year .
So after 4 years ,its value will become = 32400-4x2700
=32400-10800=21600
Hence the value of the camera equipment 4 years after it is purchased will depreciate to 21600 .
