Answer:
The value of her account after 25 years, if she stays true to the plan is:
= $152,823.31.
Step-by-step explanation:
a) Data and Calculations:
Initial deposits = $35,000
Period of investment = 25 years
Interest rate per year = 3.5% compounded continuously
Annual deposit into the same account = $1,800
Period of investment = 25 at 3.5% interest rate
Total value of her IRA account after 25 years:
Future value of $35,000 = $82,713.57
Future value of $1,800 yearly = 70,109.74
Total future value = $152,823.31
From an online financial calculator:
N (# of periods) 25
I/Y (Interest per year) 3.5
