PV = P(1 - (1 + r)^-n) / r; where P is the periodic withdrawal = $100,000; r = rate = 5% = 0.05; n = number of periods = 20 years.

PV = 100000(1 - (1 + 0.05)^-20) / 0.05 = 100000(1 - 1.05^-20) / 0.05 = 100000(1 - 0.3769) / 0.05 = 100000(0.6231) / 0.05 = 100000(12.4622) = 1,246,221 ≈ $1,250,000

Answer:

The correct option is b.

Step-by-step explanation:

Given information:APR= 5%, Period = 20 years, Annual salary = $100,000.

The formula for ordinary annuity is

[tex]PV=\frac{P[1-(1+r)^{-n}]}{r}[/tex]

Where, P is periodic payment, r is rate per period and n is number of periods.

[tex]PV=\frac{100000[1-(1+0.05)^{-20}]}{0.05}[/tex]

[tex]PV=1246221.03425[/tex]

[tex]PV\approx 1,250,000[/tex]

Therefore the correct option is b.
