Calculating average and total costs

A manufacturing plant has a potential production capacity of 1000 units per month (capacity can be increased by 10% if the 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 cost per unit is $100. Above 80 and up to 90%, variable costs on this additional output increases 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 100% and up to 110% of capacity, extensive subcontracting work is used and the unit variable costs of these additional units are 50% above those at output levels up to 80% of capacity. At 80% of capacity, the plant's 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 attached table.
