Morrison's Company heats iron jewels to high temperature by placing them in large ovens. The heated jewels are then run through a machine that forms them into shapes. Due to the length of time it takes for the oven to heat up, it is never turned off. When the jewels 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 Jewels is ready to be heated. The following information shows the jewels processed and the electricity cost over the past 11 months. 1. Using the high-low method, estimate a cost formula for power costs. Express the formula in the from of Y=a+bX. 2. Predict total electricity cost in a month when 180 jewels are processed
