To determine
To calculate:
Linear revenue function to represent the revenue R(x) for selling x necklaces. The rent for studio, Internet service, and phone come to $640permonth. Estimated cost is $3.50 to make one necklace. Cost at art shows and online is $25 each.
c)
To determine
To calculate:
(R−C)(x) and interpret its meaning in the context of this problem, where function is R(x)=25x and C(x)=3.5x+640
d)
To determine
To calculate:
The profit if the artist sells 212 necklaces during a one-month period, where function is (R−C)X=21.5x−640
Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution.
Remember that:
A matrix is in row echelon form if
Any row that consists only of zeros is at the bottom of the matrix.
The first non-zero entry in each other row is 1. This entry is called aleading 1.
The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.

Please help I'm a working mom trying to help my son last minute (6th grader)! Need help with the blank ones and check the ones he got with full calculation so we can use it to study! Especially the mixed number fractions cause I'm rusty. Thanks in advance!
