If *[tex \LARGE P] monetary units are invested, one part at *[tex \LARGE r_1] percent interest and the rest at *[tex \LARGE r_2] percent interest for one year and *[tex \LARGE I] monetary units are received in interest overall at the end of the year, then if *[tex \LARGE x] monetary units is the amount invested at *[tex \LARGE r_1], then the following relationship holds:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{r_1}{100}(x)\ +\ \frac{r_2}{100}(P\ -\ x)\ =\ I]


Plug in your numbers and solve for *[tex \LARGE x]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
