A manufacturing plant has a potential production capacity of 1,000 units per month (capacity
can be increased by 10 % if subcontractors are employed). The plant is normally operated at
about 80% of capacity. Operating the plant above this level significantly increases variable costs
per unit because of the need to pay the skilled workers higher overtime wage rates. For output
levels up to 80 % of capacity, variable costs per unit is $100. Above 80 % and up to 90 %,
variable costs on this additional output increase by 10 %. When output is above 90% and up to
100 % of capacity, the additional units cost an additional 25% over the unit variable costs for
outputs up to 80% of capacity. For production above the 100 % and up to 110% of capacity,
extensive subcontracting work is used and the unit variable costs of these additional unit are
50% above those at output levels up to 80% of capacity. At 80% of capacity, the plant fixed
costs per unit are $50. Total fixed costs are not expected to change within the production range
under consideration. Based on the preceding information, complete the following table.
