Answer
$164.85$ billion dollars
Work Step by Step
The flow of rate of the investment stream can be expressed as: $R(t)=(182.52)(0.1)(1+\dfrac{5}{100})^t=18.252(1.05)^t $ dollars per year billion .
We have: $r=0.048$ and $T=9 \ years$
The future value is equal to: $\int_0^9 18.252(1.05)^t e^{0.048 (9-t)} \ dt =253.92 $ billion dollars
Therefore, the present value is equal to:$\dfrac{\ Future Value}{e^{rT}}=\dfrac{253.92}{e^{(0.048)(9)}}=164.85$ billion dollars
