a. Develop a linear trend equation for the following data on demand for white bread loaves at a bakery (use of Excel’s Trendline, with display Equation on chart option, is recommended), and use it to forecast demand on day 16.

b, The variations around the linear trend line seem to have above- and below-the-line runs. Therefore, use trend-adjusted exponential smoothing with a = .3 and β = .2 to model the bread demand. Use tire first four days to estimate the initial smoothed series (use the average of the first four days) and smoothed trend (use tire increase from day 1 to day 4 divided by 3). Start forecasting day 5. What is the forecast for day 16?
