Consider the following actual and forecast demand levels for Big Mac hamburgers at a local McDonald’s restaurant:

DAY ACTUAL DEMAND FORECAST DEMAND Monday 88 88 Tuesday 72 88 Wednesday 68 84 Thursday 48 80 Friday The forecast for Monday was derived by observing Monday’s demand level and setting Monday’s forecast level equal to this demand level.

Subsequent forecasts were derived by using exponential smoothing with a smoothing constant of 0.25. Using this exponential smoothing method, what is the forecast for Big Mac demand for Friday?
