Full Serve Inc. has a number of divisions. One division, Gamma, makes zippers that are used in the manufacture of boots. Another division, Delta, makes boots that use the zippers and needs 95,000 zippers per year. Gamma incurs the following costs for one zipper: Direct materials $0.25 Direct labor 0.22 Variable overhead 0.97 Fixed overhead Total 1.40 $2.84 Gamma has the capacity to make 960,000 zippers per year, but because of a soft market, it only plans to produce and sell 630,000 zippers next year.

What is the ceiling of the bargaining range, and which division sets it? $2.70; Delta $4.00; Delta $2.70; Gamma $3.50; Gamma
