Need help with comment on comparative total costs per unit under traditional costing and ABC for this question.

Combat Fire, Inc. manufactures steel cylinders and nozzles for two models of fire extinguishers: (1) a home fire extinguisher and (2) a commercial fire extinguisher. The home model is a high-volume (54,000 units), half-gallon cylinder that holds 2 1/2 pounds of multi-purpose dry chemical at 480 PSI. The commercial model is a low-volume (10,200 units), two-gallon cylinder that holds 10 pounds of multi-purpose dry chemical at 390 PSI. Both products require 1.5 hours of direct labor for completion. Therefore, total annual direct labor hours are 96,300 or [1.5 hours (54,000 + 10,200)]. Expected annual manufacturing overhead is $1,584,280. Thus, the predetermined overhead rate is $16.45or ($1,584,280 96,300) per direct labor hour. The direct materials cost per unit is $18.50 for the home model and $26.50 for the commercial model. The direct labor cost is $19 per unit for both the home and the commercial models.
