n, the number of loaves of bread donated

Answer 1

To find the number of loaves of bread \( n \) that the supermarket has donated after \( w \) weeks, you can use a simple linear function. Here’s the rule:

\[ n = 25w \]

Where:

• \( n \) is the total number of loaves of bread donated,
• \( w \) is the number of weeks that have passed, and the supermarket donates 25 loaves each week.

You can express this as an input-output relationship:

Input (w) → Output (n)
\[ w \xrightarrow{} n = 25w \]

For example:

• If \( w = 1 \): \( n = 25 \times 1 = 25 \)
• If \( w = 2 \): \( n = 25 \times 2 = 50 \)
• If \( w = 3 \): \( n = 25 \times 3 = 75 \)
• And so on.
