<PRE><B>Question 170396</B>
Sarah invested $5000 in two funds, paying 7% and 9% annual interest respectively. If the total interest earned for the year was $375, how much was invested at each rate? 
---------------------------
Interest Equation: 0.07x + 0.09(5000-x) = 375 dollars
7x + 9(5000-x) = 37500
7x + 45000 -9x = 37500
-2x = -7500
x = $3750.00 (amt. invested at 7%
5000-3750 = $1250 (amt. invested at 9%)
=========================================
