S o l v e f o r n : D / A \times {1 - \frac{P \times (\frac{{(1 + i)}^{n} \times i}{{(1 + i)}^{n} - 1})}{(P \times (\frac{{(1 + i)}^{r} \times i}{{(1 + i)}^{r} - 1})) - \frac{R}{i} \times [(\frac{1}{n} + i) \times (\frac{{(1 + i)}^{r} \times i}{{(1 + i)}^{r} - 1}) - (\frac{1}{n} + i) \times (\frac{{(1 + i)}^{n} \times i}{{(1 + i)}^{n} - 1})]}} - 1 = 0
