(a) Calculate the activity-based overhead rates for each of the three cost pools, and determine the overhead cost assigned to each product line. (Round overhead rate for supervision to 2 decimal places, e.g. 15.25\% and other answers to 0 decimal places, e.g. 25,000 .) Calculate the operating income for each product line using the activity-based overhead rates. (Enter negative amounts using a negative sign preceding the number e.g. -45 . Round answers to 0 decimal places, e.g. 1,525.) Crane sells window coverings to both commercial and residential customers. The following information relates to its budgeted operations for the current year: The controller, Kimberly Young, is concerned about the residential product line.

As a result, she has decided to take a closer look at the overhead costs assigned to the two product lines to determine whether a more accurate product costing model can be developed. Following are the three activity cost pools and related information she developed: (b) The parts of this question must be completed in order.
