1.
Q=12,000
Fixed cost=8000
Average variable cost=1
Total variable cost=AVC*Q
=12000*1
=12000
TC=TVC+TFC
=12000+8000
=20000
Average total cost=TC/Q
=20000/12000
=1.66
2.
Q=22000
TFC=12,000
AVC=0.75
TVC=0.75*22000
=16,500
TC=TFC+TVC
=12,000+16,500
=28,500
ATC=TC/Q
=28,500/22,000
=1.295
3.
Q=30,000
TFC=24,000
AVC=0.25
TVC=AVC*Q
=0.25*30000
=7500
TC=24000+7500
=31,500
ATC=31,500/30000
=1.05
Third choice leads to lowest average total cost.
It means quantity 30,000 leads to lowest average total cost.
