To determine how much each pen cost, we start by noting that Brenda spent a total of [tex]$80 on ten pens. To find the cost per pen, we need to divide the total cost by the number of pens.
Here are the steps:
1. Write down the total amount spent, which is $[/tex]80.
2. Write down the number of pens purchased, which is ten.
3. To find the cost of each pen, divide the total amount spent by the number of pens:
[tex]\[
\text{Cost per pen} = \frac{\text{Total cost}}{\text{Number of pens}}
\][/tex]
4. Substituting the given values:
[tex]\[
\text{Cost per pen} = \frac{80}{10}
\][/tex]
5. Performing the division:
[tex]\[
\frac{80}{10} = 8
\][/tex]
Therefore, each pen costs [tex]$8.
So, the correct answer is:
A. $[/tex]8
