Answer:
it will need income for 121,363.12
Explanation:
We will adjust the 50,000 principal by inflation at 3% per year during 30 years:
[tex]Principal \: (1+ r)^{time} = Amount[/tex]
Principal 50,000.00
time 30.00
rate 0.03000
[tex]50000 \: (1+ 0.03)^{30} = Amount[/tex]
Amount 121,363.12
An income for 121,363.12 per year in 30 years will have the same purchasing power as 50,000 dollars today.
