Answer:
Results are below.
Step-by-step explanation:
First, we need to calculate the money required at the time of retirement:
FV= 240,000*25= $6,000,000
Now, using the following formula, we can determine the annual investment:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (6,000,000*0.039) / {[(1.039^17) - 1]
A= $255,373.88
