To determine the value of \( X \), which represents the average percentage of full price sales over the three months, follow these steps:
1. Identify the percentages of full price sales for each month:
- Month 1: 0.98
- Month 2: 0.96
- Month 3: 0.808
2. Calculate the average of these percentages:
- Add the full price sales percentages for all three months: \( 0.98 + 0.96 + 0.808 \)
- Sum: \( 0.98 + 0.96 + 0.808 = 2.748 \)
3. Divide the sum by the number of months (3):
- Average percentage: \( \frac{2.748}{3} = 0.916 \)
4. Round the result to the nearest hundredth:
- Rounded value of \( 0.916 \) is \( 0.92 \)
Therefore, the value he should use for \( X \) is \( 0.92 \).
Among the given options, the correct value is:
- \( 0.92 \)
So, the store owner should use [tex]\( 0.92 \)[/tex] for [tex]\( X \)[/tex].
