Consider the following additional information about these two products. If activity-based costing is used to allocate overhead cost, (a) compute overhead activity rates, (b) allocate overhead cost to Product A and Product B and compute overhend cont per unit for each, and (c) compute product cost per unit for each. (Round your final answers to 2 decimal places.) Consider the following additional information about these two products.
