The monthly cost \( y \) can be expressed as a function of the number of additional users \( x \) in the household. The base cost for a single user is $9, and each additional user costs $3.
The equation that represents this is:
\[
y = 9 + 3x
\]
Where:
- \( y \) is the total monthly cost,
- \( x \) is the number of additional users.
