The steps in the patterns A and B form a sequence
The attached diagram represents dots in patterns A and B
<h3>How to draw the diagrams</h3>For pattern A, we have:
Step 2 = 10 dots
Increment of 3 dots in each step
This means that:
Step 0 = 4 dots
Step 1 = 7 dots
Step 2 = 10 dots
Step 3 = 13 dots
For pattern A, we have the following rule
When n = 0 to 3, we have:
Step 0 = 1 dot
Step 1 = 3 dots
Step 2 = 9 dots
Step 3 = 19 dots
Next, we draw the diagrams of both patterns (see attachment)

Step-by-step explanation:
Given

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:
