A total of $22,000 is invested in two corporate bonds that pay 3.5% and 5% simple interest. The investor wants an annual interest income of $890 from the investments. What amount should be invested in the 3.5% bond?
----------------------
Equations:
Quantity Eq. ::::x + y = 22000
----------
Interest Eq. ::: 0.035x + 0.05y = 890
-------------------------------------
Multiply thru Quantity by 500
Multiply thru Value by 1000
-------------------------------------
50x + 50y = 50*22000
35x + 50y = 1000*890
-------------------------------------
15x = 210,000
x = $14,000 (amt. invested at 3.5%)
