You can represent the rule as an expression using the variable \( w \) for the number of weeks and \( n \) for the total number of cans of food donated. The expression can be written as:
\[ n = 32w \]
This means that if you multiply the number of weeks \( w \) by 32 (the number of cans donated each week), you will get the total number of cans \( n \).
So, in summary:
- Input: \( w \) (number of weeks)
- Operation: Multiply by 32
- Output: \( n \) (total number of cans of food donated)
The mathematical representation is:
\[ n = 32w \]
