Q5) a)
Revenue function TR = P*q = 10,000q
Profit function π = TR - TC
π = 10,000q - 200,000 - 4q2
B) dπ/dq= 10,000 - 8q = 0
q* = 10,000/8 = 1250
π = 10,000*1250 - 200,000 - 4*12502
= 6050000
Yes Firm earning π
C) shut down price in Short run , when P = Min of AVC
AVC= 4q
Min AVC = 0
So if Price > 0, then continue to produce in Short run
D)
Min AC
AC = TC/q = 200,000/q + 4q
dAC/dq= -200,000/q2 +4 = 0
q = √50,000
q* = 223.607
P = min AC = 1788.854
So continue Production in long run .
