It indicates the required return that the company is expecting on that particular investment being evaluated. ## Answer and Explanation: 1 The present value is equal to$11,142.93.

Explanation:

The present value is determined in the following format:

 Year Cash inflows PVAF @ 5% Present value of cash inflows 1-4 $2,400 3.5459505$8,510.28 4 $3,200 0.8227025$2,632.65 Total \$11,142.93

Note:

{eq}PV_{oa}=A\times \dfrac{1-(1+r)^{-n}}{r}\\ {/eq}

where

{eq}PV_{oa} = \text{Present Value of ordinary annuity}\\ A = \text{Amount of annuity payment}\\ r = \text{interest rate}\\ n = \text{number of time periods}\\ {/eq}

Also,

{eq}PV=P\times \dfrac{1}{(1+r)^{n}}\\ {/eq}

where

{eq}PV = \text{Present Value of a single payment}\\ P = \text{Amount of payment}\\ r = \text{interest rate}\\ n = \text{number of time periods}\\ {/eq} How to Calculate the Present Value of an Annuity
