Answer:
The project is worth $2,738.57.
Explanation:
Giving the following information:
You have been offered a project paying $300 at the beginning of each year for the next 20 years. The rate of return is 9%.
To calculate the present value, first, we need to calculate the final value:
FV= {A*[(1+i)^n-1]}/i
A= annual pay= 300
n= 20
i= 0.09
FV= {300*[(1.09^20)-1]}/0.09
FV= $15,348.06
Now, we can calculate the present value:
PV= FV/(1+i)^n
PV= 15,348.06/1.09^20= $2,738.57
