represent the number of months.

Response area m+
Response area

Answer 1

To represent the total cost \( C \) Joseph would charge for the cell phone data plan based on the number of months \( m \), we can write the expression as follows:

\[ C = 21 + 55m \]

Here:

• \( 21 \) is the one-time startup fee.
• \( 55m \) represents the monthly charge of $55 per month for \( m \) months.

So the completed expression is:

Response area: \( m + 21 + 55m \)

However, for clarity in terms of cost, it's better to keep it as \( 21 + 55m \).
