Row 1. Here you have the sum
Meat+
Beans+
Rice, so the expression represent the
the total price of all the food.
Row 2. Here you have the sum
Beans+
Rice. Since both foods are plants, the expression represent
the total price of the foods from plants.
Row 3. Here you have the sum
Meat+
Beans+
Rice again, so the expression represent the
the total price of all the food.
Row 4. Here you have the sum
Beans+
Meat. Since beans and meat are both rich in proteins, the expression represent
the total price of the foods rich in protein.
Row 5. Here you have the sum
Meat+
Rice. Since meat is not a plant and rice is not rich in protein, the correct answer is
None of these.
Row 6. Here you have the sum
Beans+
Meat again just in a different order. Since beans and meat are both rich in proteins, the expression represent
the total price of the foods rich in protein.
