Let $x$ denote the number of ounces of A and $y$ the
number of ounces of Y.

Then the number of units of fat are:

$x+y \ge 6$.

The number of units of protein:

$x+y \le 7$

The number of units of carbohydrate:

$2x+y \ge 10$

The above together with $x \ge 0$ and $y \ge 0$ are
the constraints, and the objective to minimise is the cost:

$cost=0.12x+0.08y$.

I hope that helps.
