The function C (n) = 12n + 5 gives the cost to order a necklace n, including a flat rate shipping charge. Which of the following inputs does not make sense in the context of this scenario? Options: C(10), C(500),C(-20)

Answer 1

In the context of the function \( C(n) = 12n + 5 \), the variable \( n \) represents the number of necklaces ordered. Since it doesn't make sense to order a negative quantity of necklaces, the input \( C(-20) \) does not make sense in this scenario.

Thus, the input that does not make sense is C(-20).
