Question

which equation expresses the orders total cost, c, as a function of the number of necklaces, n? c(n)=7n + 6 complete which expression means “the total cost, including shipping, of 5 necklaces”? n(5) c(5) c(5)+6

Explanation:

Step1: Recall function - evaluation concept

The function $c(n)=7n + 6$ represents the total cost $c$ as a function of the number of necklaces $n$. To find the total cost of a specific number of necklaces, we substitute that number into the function.

Step2: Substitute $n = 5$

When we want to find the total cost of 5 necklaces, we replace $n$ with 5 in the function $c(n)$. So the expression for the total cost of 5 necklaces is $c(5)$.

Answer:

$c(5)$
