represent the number of months.

Response area m+
Response area



The total cost for 6 months is $Response area.

Answer 1

To represent the total cost for Joseph's cellphone data plans, we can create an expression. The total cost will include the one-time startup fee plus the monthly fee multiplied by the number of months (m).

The expression will be:

\[ \text{Total Cost} = 21 + 55m \]

Now, if we want to calculate the total cost for 6 months (where \( m = 6 \)), we can substitute \( m \) with 6 in the expression:

\[ \text{Total Cost} = 21 + 55(6) \]

Calculating the monthly charges:

\[ 55 \times 6 = 330 \]

Now, add the startup fee:

\[ \text{Total Cost} = 21 + 330 = 351 \]

So, for the total cost for 6 months, it is $351.

Final Answers: Response area for the expression: 21 + 55m
The total cost for 6 months is: $351.
