1.Fungsi = TC = 30.000 + 50 Q + Q2 a. AC ? b. MC c. TC pada MC minimum

MC = ∆TC
MC = 50 + 2Q

MC minimum = 0
0 = 50 + 2Q
–2Q = 50
Q = ||–25|| = 25 (krn tidak ada jmlh barang negatif)

TC = 30.000 + 50Q + Q²
= 30.000 + 50(25) + (25)²
= 30.000 + 1250 + 625
= 31.875

AC = TC/Q
AC = 31.875/25
AC = 1.275
