Answer
The number of sweatshirts that were not adult sizes is \( s - 19 \).
Solution
To find the number of sweatshirts that were not adult sizes, we can use the following steps:
1. **Identify the total number of sweatshirts sold**: This is given as \( s \).
2. **Identify the number of adult size sweatshirts sold**: This is given as 19.
Now, to find the number of sweatshirts that were not adult sizes, we can subtract the number of adult size sweatshirts from the total number of sweatshirts sold.
The expression can be written as:
\[
s - 19
\]
Thus, the expression that shows how many sweatshirts were not adult sizes is \( s - 19 \).

Simplify this solution Bonus Knowledge
To find the number of sweatshirts that were not adult sizes, you can simply subtract the number of adult sizes (19) from the total number of sweatshirts sold (\( s \)). The expression would be \( s - 19 \). This means if the team sold 100 sweatshirts, 81 of them would be non-adult sizes! You can easily adjust this expression if more information is added. For instance, if a specific number of youth or kids' sizes is given, just modify the constant in the equation. This type of flexibility makes variable expressions super useful in real-life scenarios!
