A coffee shop owner wants to estimate demand for the next four quarters for hot chocolate. Sales data consist of trend and seasonality. Quarter relatives are 1.06 for the first quarter, 1.00 for the second quarter, 0.83 for the third quarter, and 1.11 for the fourth quarter. Using the appropriate values of quarter relatives and the equation Ft 196 +6.6t for the trend component, estimate demand for periods 9-12. (Round all calculations to two decimal points.) Demand Period 9 Demand Period 10 Demand Period 11 Demand Period 12
