<PRE><B>Question 947635</B>
Phyllis invested 35000 dollars, a portion earning a simple interest rate of 5 percent per year and the rest earning a simple interest rate of 6 percent per year. After one year the total interest earned on these investments was 1980 dollars. How much money did she invest at each rate? 
----------
Equation::
interest + interest = interest
0.05x + 0.06(35000-x) = 1980
5x + 6*35000 - 6x = 198000
----------------------------
-x = -12000
----
x = $12000 (amt. invested at 5%)
35000-x = $23000 (amt. invested at 6%)
-----------
