Answer:
$960 into 6% account and $1600 into 8% account
Step-by-step explanation:
Let money put in 6% account be x
let money put in 8% account be y
How much interest did she earn?
2560 * 0.0725 = $185.6
Now, we can write:
0.06x + 0.08y = 185.6
and we know
x + y = 2560
We can say:
x = 2560 - y
and we put this into 1st equation:
0.06(2560 - y) + 0.08y = 185.6
153.6 - 0.06y + 0.08y = 185.6
0.02y = 32
y = 1600
and thus, x = 2560 - 1600 = 960
She put $960 into 6% account and $1600 into 8% account
