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 Required: 2. Usino the hioh-fow method. estimate a cost formula for bower costs. Exoress the formula in the form Y=a+bX Required: 2. Using the high-low method, estimate a cost formula for power costs. Express the formula in the form Y=a+bX 3. Predict total power costs in a month when 144 ingots are processed
