Answer:
$51.30
Step-by-step explanation:
76 decrease 25% =
76 × (1 - 25%) = 76 × (1 - 0.25) = 57
57 decrease 10% =
57 × (1 - 10%) = 57 × (1 - 0.1) = 51.3
Bare with me a minute, I am still trying to figure it out. Here is what I have so far.
Operations that can be applied to a matrix in the process of Gauss Jordan elimination are :
replacing the row with twice that row
replacing a row with the sum of that row and another row
swapping rows
Step-by-step explanation:
Gauss-Jordan Elimination is a matrix based way used to solve linear equations or to find inverse of a matrix.
The elimentary row(or column) operations that can be used are:
1. Swap any two rows(or colums)
2. Add or subtract scalar multiple of one row(column) to another row(column)
as is done in replacing a row with sum of that row and another row.
3. Multiply any row (or column) entirely by a non zero scalar as is done in replacing the row with twice the row, here scalar used = 2
