Answer:
FV= $94,108.42
Step-by-step explanation:
First, we need to calculate the future value of the 12 annual deposits:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {3,500*[(1.06^12) - 1]} / 0.06
FV= $59,044.79
Now, the future value at the end of the 20 years (8 years more):
FV= PV*(1 + i)^n
FV= 59,044.79*(1.06^8)
FV= $94,108.42
