## Question:

## Annuity:

In the context of Finance, an annuity is a streak of periodic investments or payments made for a given investment horizon. The mechanism of annuity is generally resorted to when one has to accumulate significant retirement fund by making relatively small and regular annual investments.

## Answer and Explanation: 1

The calculated value of the annual investment to be made every year for 20 years is **option (c) $2,185**.

The value of the annual investment amount is given by:

- {eq}P = F * \dfrac{i}{(1 + i)^ {n} - 1} {/eq}

where;

F = future value of the annuity = $100,000

P = annual investment amount

i = interest rate = 8% (or 0.08)

n = number of years = 20 years

{eq}P = 100,000 * \dfrac{0.08}{(1 + 0.08)^ {20} - 1} {/eq}

{eq}P = $2,185.22 {/eq}
