Answer 1

Answer:

Fore cadet for fourth quarter us $1085

Explanation:

One Quarter = 3 months

Demand for quarter 1 = 325 + 440 + 450 = 1215

Quarter Demand in Each Quarter Weighted Forecast

1 1215

2 1280

3 1125

4 1610

6 1220

7 1055

8 1085

Weighted moving Average Forecast = ((0.25 * 1010) + (0.25 * 1220) + ( 0.5 * 1055) = 1085

Forecast for the fourth quarter is 1085
