Question 1048586: Kristina invests a total of $28,000 in two accounts paying 11% and 5% annual interest, respectively. How much was invested in each account if, after one year, the total interest was $2,270.00.
Answer by addingup(3677)   (Show Source):
You can put this solution on YOUR website! If she has 28,000 and invests an unknown amount I will call x at 11%, then she has 28,000-x to invest at 5%
:
0.11x+0.05(28,000-x) = 2,270
0.11x+1400-0.05x = 2,270
0.06x = 870
x = 14,500 is invested at 11% and
28,000-14,500 = 13,500 is invested at 5%
Happy learning,
John
