Answer:
x (Falafel) = $5.50
y (Turkey BLT) = $7.50
z (Paninis) = $6.00
Step-by-step explanation:
Step 1: Write out systems of equations
5x + 15y + 20z = 260
8x + 18y + 14z = 263
12x + 16y + 12z = 258
There are multiple ways to solve for this systems of equations. I will use an augmented matrix for this:
Top row: [5 15 20 | 260]
Middle row: [8 18 14 | 263}
Bottom row: [12 16 12 | 258]
We find RREF form of the augmented matrix to find our answers:
Top row: [1 0 0 | 11/2]
Middle row: [0 1 0 | 15/2]
Bottom row: [0 0 1 | 6]
And we have our answer!

for example if you had 5ft. for length and 6ft. for width you would times the two to get you area
Answer:
12 pens
Step-by-step explanation:
Let the variable that can be used to determine the number of pens that Kamila bought be represented by n.
Price of a notebook = $1.59
Price a pen = $0.29
Total amount spent = $5.07
But,
1.59 + 0.29 n = 5.07
So that,
0.29 n = 5.07 - 1.59
0.29 n = 3.48
n = 
= 12
Therefore, Kamila bought 12 pens.
