Using a phone card to make a long distance call costs a flat fee of $0.80 plus $0.33 per minute starting with the first minute. Write a function for the cost of a long distance call C(x) in terms of x minutes for this situation.

C = .80 + .33x

C(x)=.80+.33x

To write the function for the cost of a long distance call, C(x), in terms of x minutes, we can follow these steps:

1. Identify the flat fee: In this case, the flat fee is $0.80, which remains constant regardless of the number of minutes.

2. Determine the cost per minute: In this case, the cost per minute is $0.33, which applies to each minute starting from the first minute.

3. Calculate the cost of the call: Multiply the number of minutes, x, by the cost per minute ($0.33), and add the flat fee ($0.80).

So, the function for the cost of the long distance call, C(x), can be written as:

C(x) = flat fee + (cost per minute * number of minutes)
= $0.80 + ($0.33 * x)

Therefore, the function for the cost of the long distance call is C(x) = $0.80 + ($0.33 * x).
