Capital Value An investment produces a perpetual stream of income with a flow rate of

Elodia [21]

Answer:

$30,000

Step-by-step explanation:

The capital value is given by

$\int_{0}^{\infty} R(t) e^{-r t} dt$

where R(t) is annual rate

r - annual rate of interest

capital value $= \int_{0}^{\infty} 1200 e^{0.03t} e^{-0.07 t} dt$

= lim at b tend to infinity $\int_{0}^{b} 1200 e^{0.03t} dt$

=lim at b tend to infinity $\left [ \frac{1200}{-0.04} e^{-0.04 t} \right ]_0^b$

-30,000 { lim at b tend to inifinity $(e^{-0.04 b) = e^0]$

As $b\rightarrow \infty, e^{-0.04 b} \rightarrow 0$

$\int_{0}^{\infty} 1200 e^{0.03t} e^{-0.07 t} dt = -30,000(0 -1) =$30,000$
