Question 802153
A financial planner wants to invest 8000 some in stocks earning 15% annually and the rest in bonds earning 6% annually. 
How much should be invested at each rate to get a return of 930$ annually from the two investments?
-----------------------
Equations:
Quantity Eq:::   f + s = 8000
Interest Eq::: 15f +6s = 93000
---------
Modify for elimination::
6f + 6s = 48000
15f+ 6s = 93000
------
9f = 45000
f = $5000 (amt. invested at 15%)
-------
Solve for "s":
f + s = 8000
s = $3000 (amt. invested at 6%)
