Type in your numerical answer only; do not type any words or letters with your answer.

1.2 servings of broccoli and 1 servings of salmon.

1.2 servings of broccoli are needed.

Explanation:

Let the servings of broccoli be x an salmon be y.

One serving of broccoli contains 50 calories and 5 grams of protein.

One serving of salmon contains 140 calories and 21 grams of protein.

Calories in x servings = 50 x

Calories in y servings = 140y

Total calories when combined = 200 cal

50 x + 140 y = 200 cal ... [1]

Proteins in x servings = 5x

Proteins in y servings = 21y

Total proteins when combined = 27 g

5x + 21y = 27 ... [2]

On solving [1] and [2] we get:

x = 1.2, y = 1

1.2 servings of broccoli and 1 servings of salmon.

1.2 servings of broccoli are needed.
