Question

Joan Arlington has twice as much money invested at 5% simple annual interest as she does at 4%. if her yearly income from the two investments is $266, how much does she have at each rate?

Answer 1

Let the amount invested at 4% be $100X

THEN , the amount invested at 5% WILL BE $200X

Interest earned = 4X + 10X = 266

14X = 266

X = 19
