From now on I am just going to post a question with my guess and if you guys could tell me if I am right or wrong that would be Awesome!!
~Thanks Dylan:)

Julia finds a texting plan that costs a flat fee of $20 per month for 120 texts, plus $.20 per text after that. Which cost function represents this scenario if x equals the number of texts exceeding 120 that Julia sends in a month?

C(x) = 120 + .20x

C(x) = .20+ 120x

C(x) = 20+ .20x
