A manager uses this equation to predict demand for landscaping services: Ft = 7 + 5t. Over the past eight periods, demand has been as follows: Period, t: 1 2 3 4 5 6 7 8 Demand: 13 18 18 28 28 33 38 43 Compute the tracking signals for Periods 1-8. (Negative values should be indicated by a minus sign. Round your intermediate calculations and final answers to 3 decimal places.) Period, t Tracking signal : 1 2 3 4 5 6 7 8
