Answer:
$300,000
Step-by-step explanation:
Labor cost = $11,000
Parking cost= $7,000
Parking Labor cost = $ 18,000

Making Parking Revenue the subject of the formula, we have:
Parking Revenue = (100 x 18,000)/6
= $300,000
The augmented matrix is,

We have given system of linear equation is,

<h3>What is the meaning of augmented matrix?</h3>
In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.
So, the first row is

the second row is

and the third row is

Therefore the augmented matrix for this linear system is,
