The following formula gives the total amount of a loan PP given a monthly payment mm, an annual interest rr percent over a term of NN months. Which of the following would give us the monthly payment mm in terms of P,r,P, r, and NN?

P=(1+r1,200)N1(r1,200)(1+r1,200)Nm P = \frac{\left( 1+\dfrac{r}{1{,}200} \right)^N - 1 } { \left( \dfrac{r}{1{,}200} \right) \left( 1 + \dfrac{r}{1{,}200} \right)^N} m
