2. Compute the product margins for B300 and T500 under the activity-based costing system. (Negative product margins should be indicated by a minus sign. Round your intermediate calculations to 2 decimal places.)

3. Prepare a quantitative comparison of the traditional and activity-based cost assignments. (Do not round your overhead rate. Round your other intermediate calculations and final answers to the nearest whole number. Round your "Percentage" answer to 1 decimal place. (i.e. .1234 should be entered as 12.3))
