Question

This is for a Linear Algebra class. Please provide answer including matrices since this is linear algebra.

Step 1

Let x represent the intake of Annie's Organic Mac and Cheese , y represent the intake of Applegate's Organic beef hot dog and z represent the serving of Trader Joe's frozen Petite Peas. The corresponding equations become

Step 2

Solving for x,y,z from these equations, by Cramer's rule :

we obtain x=1.630, y=0.326, z= 0.435

Step 3
