Roary Storm and the Hurricanes Company heat gold ingots to very high temperatures by placing the ingots in a large heat coil. The heated ingots are then run through a shaping machine that shapes the soft ingot into wire. Due to the long heat-up time, the coil is never turned off. When an ingot is placed in the coil, the temperature is raised to an even higher level, and then the coil is allowed to drop to the "waiting" temperature between ingots. Management needs to know the variable cost of power involved in heating an ingot and the fixed cost of power during "waiting" periods. The following data on ingots processed and power costs are available: Number of Ingots Power Cost Month January 115 $6,035 February 95 $5,035 March 85 $4,935 April 105 $5,535 May 135 $6,535 June 125 $6,135 July 75 $4,535 August 65 $3,735 September 47 $3,935 October 37 $2,321 Required: Using the high-low method, estimate a cost formula for power cost.
