What is the approximate seasonal index for July based on the previous values of 110, 150, and 130?

To determine the approximate seasonal index for July based on the previous values of 110, 150, and 130, it's important to understand how seasonal indices are calculated. A seasonal index helps to indicate how the demand in a specific month compares to the average demand for that period.

First, calculate the average of the provided values:

• The total of the values is 110 + 150 + 130 = 390.
• The average is 390 divided by 3, which equals 130.

Next, you would compute the seasonal index for July by comparing the value for July (150 in this case) to the average:

• Seasonal index for July = Value for July / Average
• Seasonal index for July = 150 / 130 ≈ 1.1538

To convert this into an index suitable for understanding relative performance that typically ranges between 0 and 1, you may also express it as a percentage or adjust the scale when necessary. However, if the seasonal index is represented differently in the context of the choices provided, it's important to assess any further adjustment that may apply based on class principles.

Yet, when observing the values, choice B assumes a ratio or reflects back to a fundamental indexed value correlating with
