<PRE><B>Question 210866</B>
A business earned $6570 this year on an investment of $45,000 in mutual funds made last year. The two funds invested in were a pharmaceutical fund which paid out simple interest of 13% and a biotech fund which paid out simple interest of 16% . How much was invested in each fund a year ago to earn $6570 in combined interest?
---------------------------------------------
Simple Interest:
I = Prt
------------------------
x*0.13 + (45000-x)*0.16 = 6570
---
13x + 16*45000 - 16x = 657000
-3x = -63000
x = 21000 (amount invested at 13%)
45000-21000 = 24000 (amount invested at 16%
============================================
