To represent the possible ways Nina can consume 12 or more grams of protein from cheese squares and turkey slices, we need to consider the protein content for each item.
- Each cheese square provides 2 grams of protein, so if she eats \( x \) cheese squares, it adds \( 2x \) grams of protein.
- Each turkey slice provides 3 grams of protein, so if she eats \( y \) turkey slices, it adds \( 3y \) grams of protein.
To find the total protein she consumes, we can write the expression for total protein as:
\[ \text{Total Protein} = 2x + 3y \]
Nina wants to consume at least 12 grams of protein, which gives us the inequality:
\[ 2x + 3y \geq 12 \]
Therefore, the correct inequality that represents the possible ways Nina can eat 12 or more grams of protein is:
\[ 12 \leq 2x + 3y \]
So the answer is:
12 ≤ 2x + 3y
