Question 136646
The equation need to solve this problem is y=a(b)^x 
a= the starting value
b= the rate of change
x= the time

to get the rate of change do the following:
        add 1 to the percentage of change (only if value is growing)
        subtract the percentage from one   (only if value is decaying)

Since the printer is depreciating it is a decay.

The rate of change for this problem is showed below.
1-0.05  
0.95 is the rate of change.
Below is the equation for the problem.
y=35000(0.95)^4  Work the problem.
Y=35000(0.814506250
Y=28507.71875   Since we are working with money we round to two decimal places.

The printer's value after four years is $28,507.72.
