If required, round your answers to three decimal places. For subtractive or negative numbers use a minus sign even If there is a + sign before the blank (Example: -300). If the constant is "1" it must be entered in the box. Do not round intermediate calculation. )7 = 8.667 , + 3 Qtrl + 4 Qtr2 + 2 Qtr3 (c) Compute the quarterly forecasts for next year based on the model you developed in part (b).
