n, the number of cakes donated
You got it!
You can multiply w, the number of weeks, by the 12 cakes donated each week to find n, the total number of cakes. How can you represent this rule as an expression?

n, the number of cakes donated
w + 12
w divided by 12
12w

Answer 1

The correct expression to represent the rule for finding \( n \), the number of cakes donated, after \( w \) weeks is:

\[ n = 12w \]

This means that the total number of cakes donated is the number of weeks multiplied by the number of cakes donated each week (which is 12).

So the complete representation would be:

- Input: \( w \) (the number of weeks)
- Output: \( n \) (the number of cakes donated)
- Rule: Multiply by 12

In summary, the expression is \( n = 12w \).
