Can anyone help me out? Please and thank you! Answer by orca(409) (Show Source):
You can put this solution on YOUR website! If the bank offers monthly compounding, then at the end of n months the total amount, T, in their bank will be:
where P is the principal, r is the monthly interest rate.
Substituting
T = 60,000
n = 10*12 = 120
r = 8%/12 = 1/3%= 0.0033333
into the formula, we have
Solving for P, we have
So
P = 40251
