Problem $5(20\%).$ Given the parametric programming model below; explain the coefficients of the objective function; find the optimal solution and objective value for the parametric problem and report the minimum and maximum values for theta; find the optimal solution and objective value when theta is $5$; and find the optimal solution and objective value for the original form of the problem. Attach all the SAS outputs below. Do not attach the full SAS$-$screen. If I cannot read your output, the question will receive zero credits.ControlMaximize Z$(\backslash$theta $)=(10-\backslash$theta $)$x$1+(12+\backslash$theta $)$x$2+(7+2\backslash$theta $)$x$3$
