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.
