Verified step by step guidance

1. Identify the total number of pages read, which is 105 pages.
2. Identify the total number of days over which the pages were read, which is 7 days.
3. Recall that the mean (average) number of pages read per day is calculated by dividing the total pages by the total days.
4. Set up the formula for the mean: \(\text{Mean} = \frac{\text{Total Pages}}{\text{Number of Days}}\).
5. Substitute the values into the formula: \(\text{Mean} = \frac{105}{7}\), which gives the average pages read per day.
