Ishi bought a canvas and 8 tubes of paint for $24.95. If the canvas cost $6.95, how much did each tube of paint cost?

You can still ask an expert for help

Once you remove the cost of the canvas from the total price, you're left with only the cost of the 8 tubes of paint.

This is represented by

$\$24.95-\$6.95=\$18}$

If 8 tubes of paint cost $18, then all we have to do is divide 18 by 8 to get the cost of each individual tube of paint.

Thus

$\frac{\$18}{8}=\$2.25}$

is the cost for one tube of paint.

Find the linear approximation of the function

There I have found from an old tutorial notes from a Linear Algebra course I am taking that I am finding the question rather cumbersome. I haven't come across any elementary matrices problem set in this way before. I have tried to using Gauss-Jordan Elimination to reduce matrix A, whilst performing the row operations on the corresponding elementary matrix. Although, I am unsure if this is the correct approach as the problem notes that RREF calculation is not necessary.

If [A|b] denotes the augmented matrix which corresponds to the system of linear equations

$w-y=-2$

$-w+x+z=5$

$2x-y+4z=1$ ,

determine the$3\times 3$ matrix E such that [EA|Eb] is the reduced row echelon form of [A|b]. Note: You are asked to calculate the matrix E but you are not asked to calculate the reduced row echelon form.

Any help on how to approach this question or determine the matrix E would be highly appreciated.
