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? Answer C(x) = 120 + .20x C(x) = .20+ 120x C(x) = .20 + 20x C(x) = 20+ .20x
