Penjelasan dengan langkah-langkah:
Biaya produksi 1 unit = x/8 + 40 - 30/x.
Biaya produksi x unit
= x²/8 + 40x - 30
Harga jual x unit
= 100x - 5/8 x²
Keuntungan
= Harga jual - Biaya produksi
= 100x - 5/8 x² - (x²/8 + 40x
= 60x - 6/8 x²
Keuntungan maksimum, apabila K' = 0
K' = 0
60 - 12/8 x = 0
12/8 x = 60
x = 60 × 8 ÷ 12
x = 40
Keuntungan maksimum
= 60x - 6/8 x²
= 60. 40 - 6/8. 40²
= 2.400 - 1.200
= 1.200
Jadi keuntungan maksimum adalah 1.200.000.000
