We are not given tables, so will just use the amortization formula.

P=(A*((1+i)^n-1))/(i*(1+i)^n)
where
P=amount to be deposited today, to be found
A=amount withdrawn each year=18000
i=Annual interest=9%
n=number of years = 20

Substituting values,

P=(A*((1+i)^n-1))/(i*(1+i)^n)

=(18000*((1+0.09)^(20)-1))/(0.09*(1+0.09)^(20))
=164313.82 to the nearest cent
