Final answer:
To find the seasonal index for the first quarter, calculate the average sales for all four quarters and divide the sales for the first quarter by the average.
Step-by-step explanation:
To find the seasonal index for the first quarter, we need to calculate the average sales for all four quarters and then divide the sales for the first quarter by the average.
- Calculate the average sales:
(130,205,265 + 120) / 4 = 32,551,346.25 - Calculate the seasonal index:
Seasonal Index for Q1 = Sales for Q1 / Average Sales = 130,205,265 / 32,551,346.25 = 4.00 (rounded to two decimal places)
