<PRE><B>Question 1107469</B>
let x be the amount of the 22% solution
let y be the amount of the 6% solution
:
We start with what we know
:
8 * 0.28 = 2.24
y * 0.06 = 0.06y
x * 0.22 = 0.22x
:
x = y + 8
:
y = x - 8
:
This equation represents mixing the 6% solution with the 28% solution
: 
0.06(x-8) +2.24 = 0.22x
:
0.06x -0.48 +2.24 = 0.22x
:
0.16x = 1.76
:
x = 11
:
