Question

Brent was looking at his cell phone bill and saw that the total number of texts he has sent is tracked.


Month Texts
1 120
2 237
3 354
4 471


The function representing Brent's texting per month is f(m) = 117m + 3. What does the 117 represent?



A. The number of texts at the start

B. The number of the month when Brent was texting

C. The number of texts Brent had in total

D. The number of the additional texts per month

Answer 1

I am pretty sure that  the 117 represents the number of additional texts per month. To understand why I think so just subtract 237-120 you get 117 or 354-237 and so on which would have the same. So, the correct answer is D. The number of the additional texts per month
