you invested $29,000 in two accounts paying 3% and 8% annual interest, respectively. If you total the interest earned for the year was $1220, how much was invested at each rate?
-----------------------
Quantity: t + e = 29000
Interest:3t +8e = 122000
---------------------------
Modify:
3t + 3e = 3*29000
3t + 8e = 122000
-------
Subtract and solve for "e":
5e = 35000
e = $7000 (amt. invested at 8%)
-----------------------------------
t = 29000-7000 = $22000 (amt. invested at 3%)
