Macro Enterprises has the capacity to produce 10,000 chips a month, and currently makes and sells 9,000 chips a month. Chips normally sell for $6 each, and cost an average of $5 to make, including fixed costs. The monthly fixed costs are $18,000. Wolf has offered to buy 1,500 chips (all or nothing) for $4 each. The accountant has determined that the excess production (beyond capacity) can be accommodated in the short term by incurring an incremental (fixed) cost of $800. Should Wolf's offer be accepted? Why?

a. no, because it will lose $1 per unit

b. no, because the opportunity costs are less than the gains

c. yes, because the contribution from the sale exceeds the incremental costs

d. yes, because it makes $1 per unit in the short run

e. unable to determine
