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 gross profit per unit isellino Using activity-based costing, compute the overhead cost per unit for each model. (Round "Activity Rate" to 2 other answers to the nearest whole dollar amount.) Compute the total product cost per unit for each model. (Round "Activity Rate" to 2 decimal places and calculations to the nearest whole dollar amount. Round your final answers to 2 decimal places.) For each model, compute the gross profit per unit (selling price per unit minus product cost per unit). (Round "Pro per unit" and "Gross Profit" to 2 decimal places and other intermediate calculations to the nearest whole dollar am Neqative amounts should be indicated with a minus sign.)
