Which of the following inputs does not make sense in the context of this scenario?
answers
c(500)
c(10)
c(-20)

Answer 1

In the context of the function \( C(n) = 12n + 5 \):

1. **What does \( C(3) \) represent?**
- The correct answer is: **it represents the cost of buying 3 necklaces.**
- This is because \( C(3) \) calculates the total cost when ordering 3 necklaces.

2. **Which of the following inputs does not make sense in this scenario?**
- The options given are \( C(500) \), \( C(10) \), and \( C(-20) \).
- The correct answer is: **C(-20).**
- Negative values for \( n \) (the number of necklaces) do not make sense in this context, as you cannot order a negative quantity of necklaces.
