Answer:
total sales price = $21,000
Step-by-step explanation:
given data
depth = 80 feet
area = 4,800 square feet
sold = $350 per front foot
to find out
total sales price
solution
first we get here front feet that is the front length of a parcel
front feet = ...................1
front feet =
front feet = 60
so total sales price will be
total sales price = 60 × $350 per front foot
total sales price = $21,000

Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.
This multiplication is shown in the second attachment. It tells us ...
