Answer: $ 125987.80
Step-by-step explanation:
Given: The value, V(t) of $393,000 worth of assets after t years, that depreciate at 15% per year, is given by the formula
[tex]V (t)=V_o(b)^t[/tex], here [tex]V_o[/tex] is the initial asset value and b is the multiplicative decay factor.
The exponential decay function is given by ;-
[tex]f(x)=A(b)^x[/tex], where A is the initial value , x is the times period and b is the multiplicative decay factor.
where b = 1-r, r is the rate of decay.
Since r = 15%=0.15
Therefore, b = 1-0.15=0.85
Now ,for 7 years , the value of assets is given by :-
[tex]V=393000(0.85)^7=125986.795\approx125987.80[/tex]
Hence, the assets valued at after 7 years = $ 125987.80
