The present value of the sum after 3 years is $90,322.52
We will have to use formula for the present value of an annuity to solve the present value of $3,000 received at the end of each month for three years.
![PV = PMT * [(1 - (1 + r)^(-n)) / r]](https://img.qammunity.org/2024/formulas/business/high-school/owcevl2d26e3p6cq5r1r6ibc42hpwq63lc.png)
PMT = $3,000
r = 12%/12 = 0.01
n = = 3*12= 36 months
PV = $3,000 * [(1 - (1 + 0.01)^(-36)) / 0.01]
= $3,000 * 0.30107505037/0.01
= $3,000 * 30.107505037
= $90,322.5151
= $90,322.52.
