Answer:
Step-by-step explanation:
The budget is $600.
<u>Samantha spends the following amount:</u>
- 399.95 + 3*7.01 + 34.06 = 455.04
Now, she plans to buy w outfits which cost $75.88 each.
<u>The inequality for this is:</u>
<u>Solving this we get:</u>
- 75.88w ≤ 600 - 455.04
- 75.88w ≤ 144.96
- w ≤ 144.96 / 75.88
- w ≤ 1.91
w = 1 is the only integer solution greater than zero

I'm guessing on the make up of the matrices.
First off let's look at [C][F].
[C]=
[F]=
[C][F]=
where each element of [C][F] comes from multiplying a row of [C] with a column of [F].
Example: First element is product of first row and first column.
.
.
.
Now that we have [C][F], we can subtract it from [B], element by element,
[B]-[C][F]=
[B]-[C][F]=
.
.
.
If this is not how the matrices look,please re-state the problem and be more specific about the make up of the matrices (rows x columns).
Here's an example.
[A] is a 2x2 matrix. A=[1,2,3,4].
The assumption is that [A] looks like this,
[A]=
[B] is a 3x2 matrix. B=[5,6,7,8,9,10]
[B]=
