Dengan demIRI. C(25, 120). Uji titik pojok ke fungsi tujuan ffx, y) (17x 20y) 145 ribu. (x, y) (17x 20y) ribu (17 x 25 + 20 x 30) x 1000 1.025.000 (17 x 115+20 - 30) x 1000 -2.555.000 (17 x 25 + 20 x 120) x 1000 - 2.825.000 (maksimum) 30 THik Pojok y 30 A A(25, 30) 25 145 B(115, 30) x+ y= 145 Ilustrator: Zain Mustaghfir C(25, 120) Langkah 3: Melakukan uji titik pojok untuk menentukan nilai maksimum fungsi tujuan. Menentukan titik pojok daerah penyelesaian. Dari gambar terlihat titik pojok daerah penyelesaian A(25, 30), B(b, 30), dan C(25, c). Menentukan koordinat titik B. Garis x + y = 145 melalui titik B(b, 30). Substitusikan titik B(b, 30) ke dałam persamaan *+y = 145. x+ y = 145 b+30 = 145 b = 115 Dengan demikian, diperoleh koordinat titik B(115, 30). Menentukan koordinat titik C. Garis x + y = 145 meialui titik C(25, c). Dari tabel diperoleh nilai maksimum f(x, y) = (17x + 20y) ribu adalah 2.825.000. Jadi, keuntungan maksimum yang diperoleh Pak Sunu setiap hari dari penjualan kaus adalah Rp2.825.000,00.
