<PRE><B>Question 165655</B>
Eleanor invests $18,000 in two funds paying 9 1/4% and 10 1/2% simple interest. How much is invested at each rate if the total yearly interest is $1827.50?
------------------
EQUATION:
interest + interest = interest
=================================
0.0925x + 0.105(18000-x) = 1827.50
Multiply thru by 10000 to get:

925x + 1050(18000-x) = 18275000

-125x  = 18275000 - 1050*18000
-125x = -625000
x = $5000 (Amt. invested at 9 1/4 %
18000-x = $13000 (Amt. invested at 10 1/2 %
=============================================
