Question

Can you check my answer?

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?

C(x) = 150 + .20x

C(x) = 10 + .20x

C(x) = .20 + 150x

C(x) = .20 + 10x

I think it's the second choice because no other option has a flat fee of 10 dollars, but it doesn't say anything about the 150 texts so I'm not sure.

Answer 1

seems to be correct :)
