To express the relationship between the number of weeks, \( w \), and the number of cans of food donated, \( n \), you can formulate the equation as follows:
\[ n = 32w \]
In this equation:
- \( n \) represents the number of cans of food donated.
- \( w \) represents the number of weeks.
- The coefficient 32 indicates that for each week, 32 cans of food are donated.
So, for any given number of weeks \( w \), you can calculate the total number of cans donated \( n \) by multiplying \( w \) by 32.
