Answer:
P = principal; r = annual interest rate; n = number of times interest is compounded per year; t = time in years
Explanation:
Given the formula P(1 + r)^nt,
P = principal; r = annual interest rate; n = number of times interest is compounded per year; t = time in years
Compound interest is defined as interest on a loan, deposit or investment that is calculated on the basis of the principal invested, deposited or borrowed and the accumulated interest from previous periods.
