Question 437643: A woman earns $900 in interest from two accounts in a year. If she has three times as much invested at 8% as she does at 6%, how much does she have in each account? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! Part I 6.00% per annum -------------x
Part II 8.00% per annum ------------y=3x
total investment
Interest----- $900.00
6.00% x + 8.00% * 3 x = $900.00
0.06 x + 0.08 * 3 x = $900.00
0.06 x + 0.24 x = $900.00
0.3 x = $900.00
/ 0.3
x= $3,000.00 --- Part I
3x=$9,000.00 Part II
