Question

Josie finds a texting plan that costs a flat fee of $10 per month for 150 texts, plus $.20 per text after that. Which cost function represents this scenario if x equals the number of texts exceeding 150 that Josie sends in a month?

Answer 1

\[f(x) = 10+0.2x\]

Answer 2

Do you have multiple choices?

Answer 3

C(x) = 150 + .20x

C(x) = 10 + .20x

C(x) = .20 + 150x

C(x) = .20 + 10x
