You can  put this solution on YOUR website! Jorge purchased municipal bonds which yield 6% annually and certificates of deposit which yield 8% annually. If Jorge’s initial investments amount to $11,000 and the annual income is $720, how much money is invested in bonds?  
----------- 
Using one variable: 
Equation: 
int + int = int 
0.06x + 0.08(11,000-x) = 720 
----- 
6x + 88000 - 8x = 72000 
-------------- 
-2x = -16000 
x = $8000 (amt. invested at 6%) 
11000 -x = $3000 (amt invested at 8%)
