Question

Jay finds a texting plan that costs a flat fee of $15 per month for 100 texts, plus $.25 per text after that. Which cost function represents this scenario if x equals the number of texts exceeding 100 that Jay sends in a month?

Answer 1

AVAILABLE OPTIONS
C(x) = 100 + .25x
C(x) = .25+ 100x
C(x) = .25 + 15x
C(x) = 15+ .25x

Answer 2

let 'y' be the total cost.
let 'x' be be the total texts sent after 100.

Then,
total cost is $15 + 0.25 times x


So which option do you think?
