Kua tāruatia ki te papatopenga
W=0\left(100x+80\left(100-x\right)\right)
Whakareatia te 0 ki te 8, ka 0.
W=0\left(100x+8000-80x\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 80 ki te 100-x.
W=0\left(20x+8000\right)
Pahekotia te 100x me -80x, ka 20x.
W=0
Ko te tau i whakarea ki te kore ka hua ko te kore.
