joseph is selling cellphone data plans he plans to charge $55 per month for unlimited data as well as as a one time startup fee of $21 fill in expression with the correct numbers to represent the given scenario let m represent the numbers if months. the total cost for 6 months is $

Answer 1

To express the total cost of Joseph's cellphone data plan for \( m \) months, we can set up the following expression:

Total Cost = Startup Fee + (Monthly Fee × Number of Months)

Given that the startup fee is $21 and the monthly fee is $55, the expression becomes:

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

Now, to find the total cost for 6 months, we can substitute \( m = 6 \) into this expression:

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

Now, let's calculate it:

\[ 55 \times 6 = 330 \] \[ \text{Total Cost for 6 months} = 21 + 330 = 351 \]

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