Document Summary

Simplex tableau: put objective function and constraint equations in table format. Max: z 4i1 -6i2 = 0 for minimization problems, multiply by -1 and solve like a maximization problem. Max: -z + 4i1 + 6i2 = 0. 0. 5 i1 + 0. 25 i2 4(each 10 oz bottle should contain at most 4 oz of guafenesin) I1 + 3 i2 20 (each 10 oz bottle should contain at least 20 mg of pseudoephedrine. I1 + i2 = 10 (the mixture of ingredients i1 and i2 make up each 10 oz bottle) W = sum of artificial variables (a1 + a2 + + an) Max w + a1 + a2 = 0 if rhs is negative, multiply by -1 and treat normally. 10 to put tableau into proper format, get rid of coefficients of artificial variables for w. to do this, subtract each row containing an artificial variable from the phase 1 objective function (w) row.
