Nancy was attempting to estimate a model for her small business's overhead costs. She is 99.9% sure that overhead costs are driven primarily by production, but she also knows that this cost isn't entirely variable. So she grabbed the last 8 months of production and overhead cost data, listed it out, and plotted it as follows. Month # of Units Produced 1 2 3 4 5 6 7 8 200 160 230 290 310 270 220 240 Overhead Cost $2,500 1,750 2,190 2,790 2,500 2,750 2,200 2,980
