**Calculating the Average Price of College Textbooks** =====================================================

Introduction

When it comes to buying college textbooks, students often have to make a significant investment. With multiple textbooks to purchase, it can be challenging to keep track of the costs. In this article, we will explore how to calculate the average price of college textbooks, using a real-life scenario as an example.

The Scenario

Let's say a student, Will, bought 3 college textbooks. One textbook cost $32, one cost $45, and one cost $39. We need to find the average price of his books.

Calculating the Average Price

To calculate the average price, we need to add up the costs of all the textbooks and then divide by the number of textbooks.

Step 1: Add up the costs of the textbooks

Textbook 1: $32
Textbook 2: $45
Textbook 3: $39

Total cost = $32 + $45 + $39 = $116

Step 2: Divide the total cost by the number of textbooks

Number of textbooks = 3

Average price = Total cost ÷ Number of textbooks = $116 ÷ 3 = $38.67

Conclusion

Therefore, the average price of Will's college textbooks is $38.67.
