The answer is B) 9
The x values must not repeat if they are a function.
as you already know we'll be using the conjugate of -1-√(27), which is just -1 + √(27), so we can rationalize the denominator.

X pounds of $3
y pounds of $3.25
x+y = 200
300x + 325y = 320*200
300x + 325y = 64000
x+y =200
300x +325y =64000
Solve by eliminating
Multiply top one w/-300
-300y =60000
325y=64000
25y = 4000
y= 160 then
x + 160= 200
x = 40
So the mixture has;
40 pounds of $3 coffee
160 pounds of $3.25 coffee
