Answer:
It should cost $605,183.13 today.
Explanation:
Giving the following information:
Cash flow= $50,000
Number of years= 30
Interest rate= 7.25%
To calculate the present value, first, we need to calculate the final value using the following formula:
FV= {A*[(1+i)^n-1]}/i
A= cash flow
FV= {50,000*[(1.0725^30)-1]} / 0.0725
FV= $4,940,897.47
Now, we can calculate the present value:
PV= FV/(1+i)^n
PV= 4,940,897.47/ (1.0725^20)
PV= $605,183.13
