The Soft Glow Company manufactures decorative plastic candles. The process involves injecting liquid plastic resin and a very small amount of curing catalyst into candle molds, waiting for the resin to harden; opening the molds; sanding off rough spots on the plastic; and packaging the products. Growing demand encourages the Soft Glow Company to hire one additional worker for its packaging department. Soft Glow's management has a policy of paying weekly salaries even for manufacturing workers. In addition, management is very reluctant to lay-off workers unless a change in demand is permanent. How is the cost of the additional worker classified? Multiple Choice Vartable cost Fxed cost Mbxed cost Step-vaniable cost
