You can put this solution on YOUR website!
loan= $500,000
part A = 6% each year
part B = 11% each year
if the bank recieves $43,750 in interest each year, how much was loaned at 6%?
------------------------
Equations:
Quantity Eq::: x + y = 500,000
---
Interest Eq::0.11x + 0.06y = 43,750
====================
Multiply thru the 1st by 11.
Multiply thru the 2nd by 100.
--------------------------------
11x + 11y = 11*500,000
11x + 6y = 4375000
-----------------------------
Subtract the 2nd from the 1st and solve for "y":
5y = 1,125,000
---
y = $225,000 (amt. invested at 6%)
=================
500,000- 225,000 = 275,000 (amt. invested at 11%
===============================================
