    a) 88.16%

    b) 88.54%

    Explanation:

    a. Prepare a forecast for September.

    Smoothing constant (α) = 0.1

    Forecast for August (Ft) = 88%

    Actual usage for August (At) = 89.6%

    Forecast for September (Ft+1) = ?

    Ft+1 = Ft + α (At - Ft) = 88% + 0.1 (89.6 - 88) %

    = 88% + 0.16%

    = 88.16% is the forecasted usage for the month September.

    b. Assuming actual September usage of 92 percent, prepare a forecast for October usage.

    Smoothing constant (α) = 0.1

    Forecast for September (Ft) = 88.16%

    Actual usage for September (At) = 92%

    Forecast for October (Ft+1) = ?

    Ft+1 = Ft + α (At - Ft) = 88.16% + 0.1 (92 - 88.16) %

    = 88.16% + 0.384%

    = 88.54% is the forecasted usage for the month of October.
