Ret or incorrect for the work you have completed so far. It does not indicate complet Travis Metals heats copper ingots to a high temperature by placing them in a large oven. The heated ingots are then run through a shaping machine that forms them into wire. Due to the length of time it takes the oven to heat up, it is never turned off. When the ingots are placed in the oven the temperature is raised to a higher level. Once they are done being heated the oven temperature is turned back down until a new batch of ingots is ready to be heated. The following information shows the ingots processed and the power costs over the past 10 months. Month Ingots Power Cost January 148 $7,020 February 128 $6,020 March 118 $5,920 April 138 $6,520 May 168 $7,520 June 158. $7,120 July 108 $5,520 August 98 $4,720 September 68 $4,920 October 78 $3,920 13 of 3 ww September October 88 78 $4,920 $3,920 Required: 2.
