Question 1140104
Fatuma invests a total of $15,500 in two accounts paying 9% and 2% annual interest, respectively. How much was invested in each account if, after one year, the total interest was $660.00.
solution 
let amounts are x and 15500-x
interest are  0.09x and 0.
02(15500-x)
as per condition 
0.09x+0.02(15500-x)=660
0.09x-0.02x+310=660
0.07x=660-310
0.07x=350
x=350/0.07=5000
and other is 15500-5000=10500
answer $5000 at the rate of 9%  and $10500 at 2%
