If David wants to withdraw $32,635.15 every year from his account at the end if each year for 30 years, he has to have $783243.6 in the bank account .
We would use the equation for calculating present annuity.
It is written as
PV = R[1 - (1 + r)^- n]
In which.
Considering the data provided,
r = 1.5/100 = 0.015
n = 30 years
R = $32,635.15
Put the values in the formula,
PV = 32635.15[1 - (1 + 0.015)⁻³⁰]/0.015
PV = 32635.15[1 - (1.015)⁻³⁰]/0.015
PV = 32635.15(1 - 0.64)/0.015
PV = 32635.15 × 24
PV = $783243.6
Thus, amount David must have in the bank presently is $783243.6.
