Answer:

A is true.

Step-by-step explanation:

A is true because y=15x+75 means that they charge $15 for every person but $75 right away. For planner 2, they charge $20 a person because comparing coordinates 1 and 2, every 5 people charge $100. So to find the amount per person for planner 2, divide 100 by 5 and you'll get 20, and since 20 is 5 more than 15. A is true.
