Average Pastries Sold Per Day

A local bakery keeps track of the sales of three types of pastries over a week. The weekly sales data is as follows:

• Muffins: 20
• Croissants: 15
• Bread Rolls: 10

To find the average number of pastries sold per day, you need to divide the total sales for each type of pastry by the number of days (7). What is the average number of pastries sold per day across all types on a whole number basis?
