Answer :
Money accumulated at retirement after 40 year = $773,809.83
Explanation :
As per the data given in the question,
Present value of future deposits = $5,000 ÷ (1+6%) + $5,000 ÷ (1+6%)^2+... +$5,000 ÷ (1+6%)^40
= $75,231.48
Future value of deposit is
= Present value × (1 + interest rate)^number of years
= $75,231.48 × (1+6%)^40
= $773,809.83
Hence, Money accumulated at retirement after 40 year = $773,809.83
