Answer:
The total interest of $320 will be the sum of the amount earned in each account.
Step-by-step explanation:
320 = x(0.04)(1) + (5000-x)(0.08)(1)
320 = 0.04x + 400 - 0.08x
-80 = -0.04x
2000 = x
5000 - x = 3000
$2,000 was invested at 4%
$3,000 was invested at 8%
9514 1404 393

Maria first made an error in step 3.
Maria can correct her error by multiplying 136.49 by 1 over 4 before subtracting 3.0625 from it.
x= 20
y = 60
y = 3x
6(3x) = 360
3x = 360/6
3x = 60
x = 20
y = 3*20
x 4/ 64 y 10
It is 2+2
