Answer:
The computer will be worth $398.27 after 12 years.
Step-by-step explanation:
Cost of new computer = P = $2,800
Rate of loss per year = r = 15%
Time period in years = t = 12
[tex]A = P (1 - r)^t[/tex]
[tex]A = 2800(1-0.15)^{12}[/tex]
[tex]A = 2800(0.85)^{12}[/tex]
[tex]A = 2800*0.14224[/tex]
[tex]A = 398.27[/tex]
So after 12 years the computer will be $398.27 of worth.
