Question 54880
If I invest $25,000 in two different stocks.  One earns 6.5%  and the other earns 7.00%.  If the total interest earnings for one year is 1683.75, how much is invested in each stock?
------------
Let amount invested at 6.5% be "x".
Interest on this money is 0.065x dollars.
--------
Amount invested at 7% is "25000-x"
INterest on this money is 0.07(25000-x)=1750-0.07x dollars
-------------
EQUATION:
interest + interest = 1683.75
0.065x + 1750-0.07x = 1683.75
-0.005x=-66.25
x=$13,250 (amount invested at 6.5%)
25000-x=$38,250 (amount invested at 7%)
Cheers,
