(Use Excel) (Hint: Express the price p as a function of the demand x) 2. b) Find a linear best fit equation for the cost data, using x as the independent variable. (Use Excel) 3. c) By using the price-demand equation found in part (a), and cost function found in part (b), find a best fit equation for profit function P(x), using x as the independent variable. Then plot its graph using given x values in the table. (Use Excel)
