Instead of showing you how to solve this problem, I'll show you how to solve all problems of this type.


*[tex \Large P_1], a portion of *[tex \Large T] currency units, is invested at *[tex \Large r_1] percent annual interest and the other part, *[tex \Large P_2], is invested at *[tex \Large r_2] percent annual interest. After one year the accounts paid *[tex \Large Y]  currency units in interest. How much was invested at each of the interest rates?


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{r_1}{100}P_1\ +\ \frac{r_2}{100}(T\ -\ P_1)\ =\ Y].


You are given *[tex \Large r_1], *[tex \Large r_2], *[tex \Large T], and *[tex \Large Y].  Solve for *[tex \Large P_1] and then calculate *[tex \Large T\ -\ P_1\ =\ P_2]

My calculator said it, I believe it, that settles it
