A Simplex Matrix Is Given

Multiple Choice

A simplex matrix is given. In this case the solution is complete, so identify the maximum value of f and a set of values of the variables that gives this maximum value. If multiple solutions may exist, indicate this and locate the next pivot. ​ ​

A) The maximum value of f is 160 when
,
And
)
B) The maximum value of f is 160 when
