Multiple Choice

Solve the problem.
-Suppose that P dollars is invested at the end of each compounding period n times per year at interest rate r. Then the value A (in $) of the annuity after t years is given by $$A = \frac { P \left[ \left( 1 + \frac { r } { n } \right) ^ { n t } - 1 \right] } { \frac { r } { n } } .$$ An employee invests $150 per month in an ordinary annuity. If the interest rate is 4%, find the value
