Answer: B
Step-by-step explanation: the number of times they’re charging 35 depended on the number of people attending (represented by n) so you get 35n. then 100 is their set fee, meaning it won’t fluctuate. so add your 35n + 100 and you need that total to be less than or equal to 2000.. meaning your answer is B.
i hope that made sense, good luck!
