A new out-of-state distributor has offered to buy 50,000 units next month for $ 3.44 each. These units would be marketed in other states and would not affect Windtrax’s sales through its normal channels. A study of the costs of this new business reveals the following:
Direct materials costs are 100% variable.
Per unit direct labor costs for the additional units would be 50% higher than normal because their production would require overtime pay at one and one half times their normal rate to meet the distributor’s deadline.
Twenty- five percent of the normal annual overhead costs are fixed at any production level from 250,000 to 400,000 units. The remaining 75% is variable with volume.
Accepting the new business would involve no additional selling expenses.
Accepting the new business would increase administrative expenses by a $ 4,000 fixed amount.
