 A. P (1 + in) B. P(1 + i)n C. P i n D. P [(1 + i)n-1]

2.  If P represents the principal n the number of interest periods and i the interest rate based on the length of one interest period the amount of compounded interest during n interest periods is
 A. P (1 + in) B. P(1 + i)n C. P i n D. P [(1 + i)n-1]

3.  The nominal and effective interest rates are equal when the interest is compounded
