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

Choices:
C(x) = 150 + .20x

C(x) = 10 + .20x

C(x) = .20 + 150x

C(x) = .20 + 10x

Answer 2

Thank you ahead of time :)

Answer 3

Well you know...there will always be a constant charge...of 10 dollars a month for the plan...this is our constant (+ 10)

we also have a variable that we don't quite know....and that's how many texts he will go over by....it charges him .20 per text...so this can be written .20x

so if we put together that variable and that constant we get

C(x) = ???

Answer 4

umm
10.20x?

Answer 5

Not quite...when I say "put together" I mean in the same equation...not adding them

C(x) has...a constant charge + 10 and a variable charge of .20 per text .20x

Looking at your answer choices...which one does this look like?
