Answer:
114
Step-by-step explanation:
For computing the forecast value for the resulting year, we have to apply the formula which is shown below:
= Actual demand × alpha + forecast demand × ( 1- alpha)
= 90 × 0.2 + 120 × (1 - 0.2)
= 18 + 96
= 114
To compute the forecast value we have to deduct the alpha from the forecast demand and multiply the alpha with the actual demand
