Follow the step-by-step directions to determine the cost allocations for Current Designs.
(a) Composite Rotomolded
Directly assigned costs 28,000$ 40,000$
(b) Composite Rotomolded
Directly assigned costs 28,000$ 40,000$
Remaining cost allocation:
Curing time (the time that is needed for the chemical processes to
finish before the next step in the production process; many of
these costs are related to the space required in the building)

Activity based costing assigns significantly more costs to the composite kayaks. Since the cost is divided into
pools and each pool is allocated using a cost driver that is related to those particular costs, it provides a more
