Answer:
Forecast for Spring season demand year 5 = 1,680 sailboats
Explanation:
total demand:
year 1 = 4,560
year 2 = 5,590
year 3 = 5,410
year 4 = 5,040
average quarterly demand:
year 1 = 4,560 / 4 = 1,140
year 2 = 5,590 / 4 = 1,397.5
year 3 = 5,410 / 4 = 1,352.5
year 4 = 5,040 / 4 = 1,260
Spring season demand:
year 1 = 1,520
year 2 = 1,400
year 3 = 1,640
year 4 = 1,580
Seasonal factor for Spring season:
year 1 = 1,520 / 4,560 = 0.3333
year 2 = 1,400 / 5,590 = 0.2504
year 3 = 1,640 / 5,410 = 0.3031
year 4 = 1,580 / 5,040 = 0.3135
Average seasonal factors for Spring season = (0.3333 + 0.2504 + 0.3031 + 0.3135) / 4 = 0.3
Forecast for Spring season demand year 5 = 0.3 x 5,600 sailboats = 1,680 sailboats
