Question 385766
Of the $50,000 that Natasha pocketed
on her last real estate deal, $20,000 went to charity. 
-------------------------
She invested part of the remainder in Dreyfus New Leaders Fund
with an annual yield of 16% and the rest in Templeton
Growth Fund with an annual yield of 25%. If she made
$6060 on these investments in 1 year, then how much did she
invest in each fund?
-----
Equations:
Quantity Eq:::     x +  y = 30000
Interest Eq::: 0.16x+0.25y = 6060
---
Multiply the Quantity Eq. by 16
Multiply the Interest Eq. by 100
----------------------------
16x + 16y = 16*30000
16x + 25y = 606000
------------------------
Subtract and solve for "y":
9y = 126000
----
y = $14000 (amt. invested at 25%
---
Since x+y= 30000, x = $16000 (amt. invested at 16%)
==============
