B. This is the actual demand in February, not the forecasted demand for March. The formula for calculating a forecasted amount using exponential smoothing is:

Forecasted Value = (alpha × current actual value) + ([1 - alpha] × current forecasted value)

C. The formula for calculating a forecasted amount using exponential smoothing is:

Forecasted Value = (alpha × current actual value) + ([1 - alpha] × current forecasted value)

Using the forecasted and actual amounts given for the month of February, we can calculate the forecasted value for the month of March as follows:

Forecasted Value = (0.3 × 158) + (0.7 × 148)

Forecasted Value = 151

D. This is the demand forecast for February. It is not the demand forecast for March. The formula for calculating a forecasted amount using exponential smoothing is:

Forecasted Value = (alpha × current actual value) + ([1 - alpha] × current forecasted value)
