A street vendor at a parade sells fresh lemonade, soda, bottled water, and iced-tea, and the unit price for each item is given in matrix P . The number of units sold of each item is given in matrix N . Compute NP and interpret the result. Lemonade Soda Water Tea N = [ 150 270 440 80 ] P = [ $ 2.50 $ 1.50 $ 2.00 $ 2.00 ]

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.
