The total cost for 6 months is $

Answer 1

To represent the total cost of Joseph's cellphone data plan for \( m \) months, we can use the expression:

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

Here, \( 21 \) represents the one-time startup fee, and \( 55m \) represents the monthly charge of $55 multiplied by the number of months \( m \).

For \( m = 6 \), you can calculate the total cost for 6 months as follows:

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

Calculating the multiplication:

\[
55 \times 6 = 330
\]

Now, adding the startup fee:

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

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