Explanation:

Step1: Calculate the amount due for Phone Lines

The formula for the amount due is \( \text{Amount Due}=\text{\$Billed per Unit}\times\text{Usage} \).
For Phone Lines, \(\text{\$Billed per Unit}=\$41\) per line and \(\text{Usage} = 8\) lines.
So, \( \text{Amount Due}=41\times8 \).

Step2: Perform the multiplication

\(41\times8=(40 + 1)\times8=40\times8+1\times8=320 + 8=328\).

Answer:

\(328\)
