Answer 1

To find the total cost for 6 months of a cellphone data plan, we can create an expression that includes the monthly charge and the one-time startup fee.

Let:

• \( m \) represent the number of months
• The monthly charge is $55
• The one-time startup fee is $21

The expression for the total cost \( C \) can be represented as:

\[ C = 21 + 55m \]

For 6 months, substitute \( m \) with 6:

\[ C = 21 + 55(6) \]

Now, calculate it:

\[ C = 21 + 330 \] \[ C = 351 \]

Therefore, the total cost for 6 months is $351.
