Answer:
13,710
Step-by-step explanation:
The computation of the forecast for period 5 using a four period weighted moving average is shown below:
= Weights of period 1 × Period 1 + Weights of period 2 × Period 2 + Weight of period 3 × Period 3 + Weights of period 4 × Period 4
= .05 × 10000 + .15 × 12400 + .30 × 13250 + .50 × 14750
= 5,00 + 1,860 + 3,975 + 7,375
= 13,710
