The long-distance phone bill can be represented as a linear function where the total cost depends on the number of minutes $t$ called.

Here's the symbolic representation:

$C(t) = 0.4040t + 2.95$

Where:

• $C(t)$ is the total phone bill in dollars,
• $t$ is the number of minutes,
• $0.4040$ is the cost per minute in dollars (converted from 40.40 cents), and
• $2.95$ is the fixed fee in dollars.

1. How would the function change if the rate per minute was different?
2. What is the cost for a 30-minute call?
3. How can we determine the total cost for $t$ minutes without the fixed fee?
4. How does this linear function graph look for various values of $t$?
5. How would the fixed fee affect the overall cost if it were higher?

Tip: Always double-check the unit conversion, especially when working with cents to dollars.
