If you create a matrix, C, to show the inventory at the end of July, the value of the entry represented by C22 is ? In a matrix with components aij, which represents unit sales for july, the maximum possible value that a31 can have is ?

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): The entry C22

First, matrix C represents the inventory at the end of July.

The entry of C is calculated as:

i.e.

Item C22 means the entry at the second row and the second column.

From the matrix

Solving (b): The maximum A31 possible.

From the given data, we have:

From the matrices above.

A31 means entry at the 3rd row and 1st column.

So, the possible values of A31 are:

and

By comparison, 376 > 54

So:

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
