Question

Financial homework for my math class. I am trying to understand the work because I do not get it at the moment. 

Answer 1

Your question is incomplete. What is the time frame
of the loan?

A = p(1 + r/n)^nt
A = future amount to be determined
p = principal = 1900
r = interest rate = 0.09
n = number times compounded per year = 2
t = time in years

A = 1900(1 + 0.09/2)^2t
A = 1900(1.045)^2t

To finish we need the time t. How many years?
