RKR Consultants produces a monthly report on the semiconductor chip manufacturing industry for use by its consultants in serving RKR clients. The research office now being used to produce the report has fixed monthly overhead costs of \($2,000\). The research staff have a theoretical capacity to prepare another report on a second industry each month. RKR has learned that a semiconductor industry trade group produces a similar industry report that is available on a subscription basis. If RKR were to subscribe to the report from the industry trade group, the research office would be idle and 90% of the fixed costs would continue to be incurred. There are no alternative uses for the research office. The variable costs associated with preparing the monthly research report are \($500\) per report. Fixed overhead is allocated based on planned production levels. If RKR Consultants continues to use the monthly research report, it would realize a net benefit by purchasing the report from the semiconductor industry trade group only if the monthly subscription price is less than what amount?
