You deposit $18,000 into a savings account at a bank that has a rate of 66% compounded monthly. find the amount of money in the account after 44 years. 

Equation you are going to use is  where A is the amount earned, P is the initial/principal amount, R is the rate, N is the number of periods the amount is compounded, and t is the time in years.

P = 18000, R = 66% or .66, N = monthly so 12, T = 44 years.

So plugging it we get .

Type that into your calculator or an excel sheet for your answer. My calculator  (a TI-36X Pro) gives me 3.4085619516 which isn't  a very practical answer for money calculations.
