Question 648455
you invested $15,000 in two accounts paying 2% and 4% annual interest, respectively. If the total interest earned for the year was $520, how much was invested at each rate?
------------
t = amount @ 2%
f = amount @ 5%
----
t + f = 15000
0.02t + 0.05f = 520
Solve for t & f
============
PS  "respectively" contributes nothing
