Hello there. To solve this question, we'll need to set up a system of equations with 3 equations and 3 variables.
In each equation, we'll have the amounts for protein, carbohydrates and vitamin A.
Talking about protein:
Each serving of salmon steak has 30 grams of protein, baked eggs contains 20 grams of protein and acorn squash contains 4 grams of protein.
Say the servings of salmon steak, baked eggs and acorn squash are the variables x, y and z, respectively. We multiply x, y and z by the respective values for the protein of each serving and add them up. It should be equal to the amount of protein the dietitian was thinking of.
30x + 20y + 4z = 113
Talking about carbohydrates:
The same thing will apply to carbs, we multiply the variables by how many carbs we can get for eachserving. A serving of salmon steak gives you 10 grams of carbs, baked eggs gives you 3 grams of carbs and acorn squash gives you 15 grams.
10x + 3y + 15z = 54
Talking about vitamin A:
Repeat the same process, this time using the values for the vitamin A you get form each serving.
x + 20y + 37z = 135.5
Then we have the following system of equations:
Solving this system of equations, you can use the method of your choice.
After you solved it, you find the values:
1.5 serving of salmon steak, 3 servings of baked eggs and 2 servings of acorn squash.
