Newcastle Mining Company (NMC) mines coal, puts it through a one-step crushing process, and loads the bulk raw coal onto river barges for shipment to customers NMC's management is currently evaluating the possibility of further processing the raw coal by sizing and cleaning it and selling it to an expanded set of customers at higher prices. The option of building a new sizing and cleaning plant is ruled out as being financially infeasible. Instead, Amy Kimbell, a mining engineer, is asked to explore outside-contracting arrangements for the cleaning and sizing process Kimbell puts together the following summary: (Click the icon to view the summary.) Read the requirements (Click the icon to view additional information.) Requirement 1. Prepare an analysis to show whether it is more profitable for NMC to continue selling raw bulk coal or to process it further through sizing and cleaning (ignore coal fines in your analysis.) Begin by calculating the incremental sales revenue, then incremental costs and finally incremental gain or loss. (Do not round until the final answer for each cost calculation, then round to the nearest dollar. Use parentheses or a minus sign for losses.) Incremental sales revenues: Sales revenue after further processing Sales revenue from bulk raw coal Incremental sales revenue Incremental costs: Direct labor 270000000 Supervisory personnel Heavy equipment costs Sizing and cleaning Outbound rail freight Incremental costs 790,000 190,000 315000 29700000
