The linear system below represents the sales of large and small popcorn servings at a movie theater for two consecutive days.

The size of the augmented matrix for this system is:

                          2×3

We are given a system of linear equation consisting of two variables L and S as:

Hence, the system that is formed is:

where

and

and the augmented matrix is written as:

Hence, the size of the augmented matrix for this system is:

                          2×3

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
