The manufacturing cost of 5,000 units of a commodity is as follows:
Material: $20,000
Wages: $25,000
Chargeable Expenses: $400
Fixed Overheads: $16,000
Variable Overheads: $4,000
For manufacturing every 1,000 extra units of the commodity, the cost increases as follows:
(i) Material proportionately
(ii) Wages 10% less than proportionately
(iii) Chargeable Expenses: Nil
(iv) Fixed Overheads: $200 extra for every 1,000 units
(v) Variable Expenses: 25% less than proportionately
You are required to calculate the estimated cost of manufacturing 8,000 units of that commodity.
