Cranshaw Business Services $($CBS$)$ operates an information technology $($IT$)$ consulting firm out of two offices: Detroit and Los Angeles. Corporate services, such as legal, finance, and personnel, are centralized at the main office and the costs of these services are allocated to the two offices for the purposes of profitability assessment. The Detroit office is the original unit of the company and is well established, having long$-$time clients from the automotive and other manufacturing industries. The Los Angeles office is new with a smaller, much more varied, clientele. The costs of personnel services at CBS are currently allocated on the basis of the number of employees in each office. The annual costs of the personnel department total $$520,000.$ Data for the fiscal year just ended show the following:
