Question 1161650
<font face="Times New Roman" size="+2">


If you invest *[tex \Large P] monetary units in two accounts such that *[tex \Large x] monetary units is invested at r_1 percent per annum, and the rest is invested at r_2 percent per annum such that the interest amount at the end of one year is *[tex \Large I] then:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{r_1}{100}x\ +\ \frac{r_2}{100}\(P\ -\ x\)\ =\ I]


You know *[tex \Large P], *[tex \Large r_1], *[tex \Large r_2], and *[tex \Large I].  Just plug in the numbers you know, solve for *[tex \Large x], and calculate *[tex \Large P\ -\ x].

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