Ice Cool produces two different models of air conditioners. The activities, costs, and cost drivers associated with the two manufacturing processes and the support process follow. Additional production information concerning its two models follows. 1. Compute the activity rate for each activity using activity-based costing. 2. Using activity-based costing, compute the overhead cost per unit for each model. 3. Compute the total product cost per unit for each model. 4. For each model, compute the seling price per unit minus product cost per unit. Complete this question by entering your answers in the tabs below. Compute the activity rate for each activity using activity-based costing. (Round "Activity rate" to 2 decimal ploces.)
