calculate mc and avc from following data
output units 1 2 3
total cost 80 96 120
avc 60 30 20
AFC(given) 60 30 20
TFC 60 60 60
TVC 20 36 60
MC 20 16 24
AVC 20 18 20
[Note:- by AFC we can find out TFC by TFC=AFC*Q then by TVC=TC-TFC we can find TVC and then AVC=TVC/Q AVC can be found. Now for MC, it can be found out MCn=TCn-TCn-1 , MC can be found.
