You have recorded your company sales over the last 2 years and notice an increasing trend in sales. After plotting the sales in Excel, it shows you the following best-fit line: y = 1036.7x + 2729.5 where y is units sold and x is the time period. You also observe that the sales show seasonality and calculate the seasonal indices for each season in the table below. Season Winter Spring Summer Fall Seasonal Index 0.82 0.78 1.26 1.13 Using the trendline and seasonal index, what is the forecast for the next Summer (time period 11)? (Hint: this is similar to practice problem #28)
