Josie would like to have wireless Internet in her apartment. Her phone compony charges a $60 installation fee and $39.99 per month. Write an eqaution that will help Josie determine her cost (c ) to have wireless for any given number of month (m).

Options

A. `60+39.99m = c`
B. `39.99 + 60m = c`
C. `60 = 39.99m`
D. `c= 60-39.99m`

Answer

To determine the total cost \( c \) for Josie to have wireless Internet for any given number of months \( m \), we can break down the costs as follows:

1. **Identify the fixed cost**: Josie has to pay a one-time installation fee of $60. This is a fixed cost and does not depend on the number of months.

2. **Identify the variable cost**: The monthly charge for the Internet service is $39.99. This cost will accumulate based on the number of months \( m \) that Josie subscribes to the service.

3. **Calculate the total cost**: The total cost \( c \) can be expressed as the sum of the installation fee and the monthly charges for \( m \) months. The monthly charge for \( m \) months is calculated as \( 39.99 \times m \).

Putting it all together, we can write the equation for the total cost \( c \) as follows:

\[ c = 39.99m + 60 \]

This equation allows Josie to determine her total cost for any number of months \( m \).
