Compound Interest

Compound Interest: Interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan.
 
P = principal amount (the initial amount you borrow or deposit)
r  = annual rate of interest (as a decimal)
t  = number of years the amount is deposited or borrowed for.
A = amount of money accumulated after n years, including interest.
n  =  number of times the interest is compounded per year 

    Ex. 1,500 dollars is deposited in the bank paying a yearly interest rate of  4.3% compounded quarterly. what is the balance after 6 years?
P: 1,500
R: 0.043
N: 4
