Answer:

Step-by-step explanation:

Given that a company has just purchased a new computer for $3200 The company chooses to depreciate using the straight-line method for 4 years.

Since residual value is not there, we have for 4 years straight line depreciation as 3200/4 = 800 dollars.

i.e. value will be reducing every year 800 dollars

So equation will be

a)$y =3200-800x$

where y = value after x years

b)Implied domain is x =0,1,2,3,4 since after that value will be negative which is not practical

c) Enclosed

d) After 3 years book value is

$y(3) =3200-2400 =800$

e) When y =1600 we get

$1600=3200-800x\\x=2$

After 2 years
