Ответ:
A) 40
B) 0
C) -60
Step-by-step explanation:
q = 5000 - 100p
p = (5000 - q)/100
p = 50 - q/100
Revenue = pq
= (50 - q/100)q
= 50q - q²/100
dR/dq = 50 - 2q/100
dR/dq = 50 - q/50
A) q = 500,
dR/dq = 50 - (500/50) = 40
B) q = 2500,
dR/dq = 50 - (2500/50) = 0
C) q = 5500,
dR/dq = 50 - (5500/50) = -60
