Question Help
An investment pays 8% interest compounded continuously. If money is invested steadily at the rate of $15,000,
how much time is required until the value of the investment reaches $150,000?
KeN-)dt =15,000 e
,0.08(N-t)dt
r(N
Integrate with respect to t.
15,000 e e0.08(N - t)
0.08(N-1) dt = - 187,500
0.08(N – 1)|
Now, set the definite integral equal to the ending balance and isolate the exponential term.
= 150,000
%3D
-187,500 e0.08(N-1)
- 187,500 (e- e0.08N)
= 150,000
%3D
0.08N = 1.8
Take the natural logarithm of both sides and solve for N.
0.08N = 1.8
0.08N = In (1.8)
N 7.35
The amount of time required is approximately 7.35 years.
