One year an investor earned $2,750 from a $50,000 investment in bonds and stocks. She earned 4% from bonds and 6.5% from stocks. How much was invested in each?
----------------
Quantity Eq:: f + s = 50,000
Interest Eq: 4f + 65s = 275000
------------------------------------
Modify::
4f + 4s = 200,000
4f + 65s = 275000
----
Subtract and solve for "s":
61s = 75000
s = $1229.51 (amt. invested at 6.5%)
-----
f = 50000-1229.51 = $48770.49 (ant, invested at 4%)
