To find the average price of the three textbooks Will bought, we need to follow these steps:
1. Add the prices of all the textbooks together:
- The cost of the first textbook is \[tex]$32.
- The cost of the second textbook is \$[/tex]45.
- The cost of the third textbook is \[tex]$39.
When we add these together, we get:
\[ \$[/tex]32 + \[tex]$45 + \$[/tex]39 = \[tex]$116 \]
2. Calculate the average price by dividing the total cost by the number of textbooks:
- There are 3 textbooks.
So, we divide the total cost by the number of textbooks:
\[ \frac{\$[/tex]116}{3} \approx \[tex]$38.67 \]
Based on these calculations, the correct statement to calculate the average price of the books is:
D. \[ (\$[/tex]32 + \[tex]$45 + \$[/tex]39) \div 3 \]
Therefore, the best answer is: D.
