Answer:
$7,200: the funds rose 6% in one year
$2,800: the other fund rose 9% in one year
Step-by-step explanation:
X: the funds rose 6% in one year
Y: the other fund rose 9% in one year
X + Y = 10000
0.06X + 0.09Y = 684
Substitute X = 10000 - Y
0.06(10000 - Y) + 0.09Y = 684
600 + 0.03Y = 684
0.03Y = 84
Y = 2800
X = 10000 - 280
= 7200
$7200 in the fund rose 6% n $2800 in the fund rose 9%
let x be the amount in the fund rose 6%
gain in one year=x*6%=0.06x
total amount is 10000
so amount in the fund rose 9% = 10000-x
gain in one year=(10000-x)*9%=900-0.09x
total gain=0.06x+900-0.09x=900-0.03x
=684
900-684=0.03x
0.03x=216
x=7200
the other fund amount=10000-7200=2800
it could be 5 root 16? im not sure
