I am not sure, I need some help with these.
1) Rent is not part of variable cost and hence variable cost will remain same whereas average cost would come down with decrease in rent.
2) Reducing no of shift would decrease out put. Hence, both variable cost and average cost will increase and move up in the graph.
3) Variable cost would remain same if increase in productivity and wage increase proportionately. Also average cost would remain same.
4) Both variable cost and average cost would move up the graph.
5) Might cost increase in both variable and average cost in short term but can be beneficial in long term.
