A dry cleaner uses exponential smoothing to forecast equipment usage as a percentage of capacity (i.e., utilization) at its main plant. August usage was forecast to be 88 percent of capacity, whereas actual usage turned out to be 89.6 percent of capacity. A smoothing constant of 0.2 is used.

Prepare a forecast for September.

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