To find the cost of making 10 necklaces using the function \( c(x) = 2.5x + 15 \), we can substitute \( x = 10 \) into the function:
\[
c(10) = 2.5(10) + 15
\]
Calculating \( 2.5(10) \):
\[
2.5(10) = 25
\]
Now add 15:
\[
c(10) = 25 + 15 = 40
\]
Therefore, the cost to make 10 necklaces is \( c(10) = 40 \) dollars.
\[
c(10) = 2.5(10) + 15
\]
Calculating \( 2.5(10) \):
\[
2.5(10) = 25
\]
Now add 15:
\[
c(10) = 25 + 15 = 40
\]
Therefore, the cost to make 10 necklaces is \( c(10) = 40 \) dollars.
