An Accounting firm, provides consulting and tax planning services

Cost Accounting Kelly and Logan, an accounting firm, provides consulting and tax planning services. For many years, the firm's total administrative cost (currently $250,000) has been allocated to services on the basis of billable hours to clients. A recent analysis found that 65% of the firm's billable hours to clients resulted from tax planning services, while 35% resulted from consulting services. The firm, contemplating a change to activity-based costing, has identified three components of administrative cost, as follows: Staff support $180,000 In-house computing charges 50,000 Miscellaneous office costs 20,000 Total 250,000 A recent analysis of staff support found a strong correlation with the number of clients served (consulting, 20; tax planning, 60). In contrast, in-house computing and miscellaneous office cost varied directly with the number of computer hours logged and number of client transactions, respectively. Consulting consumed 30% of the firm's computer hours and had 20% of the total client transactions If Kelly and Logan switched from its current accounting method to an activity-based costing system, the amount of profits attributed to tax planning services would: A. decrease by $23,500. B. increase by $23,500. C. decrease by $32,500. D. change by an amount other than those listed above. E. change, but the amount cannot be determined based on the information presented
