<PRE><B>Question 389883</B>
Cole’s two student loans totaled $31,000. One of his loans was at 2.8% simple interest and the other at 4.5%. After one year, Cole owed $1024.40 in interest. What was the amount of each loan? 
-----
Equation:
interest + interest = interest
0.028x + 0.045(31000-x) = 1024.40
---
Multiply thru by 1000 to get:
---
28x + 45*31000 - 45x = 1000*1024
---
-17x = -371000
---
x = $21,823.53 (amt. invested at 2.8%
----
31000-x = $9176.47 (amt. invested at 4.5%
