NetBusters has a $30 sign-up fee plus $1.25 per video BlockFlix has a $10 sign-up fee plus $2.25 per video
How do I set up a function rule equation
I assume that you want to find out how many videos you have to buy before they become equal. Consider this:
There is a $20 difference in sign-up fees and a dollar difference per video. Let X = number of videos ordered.
(30-10) - (2.25-1.25X) = 0
I hope this helps. If not, repost your question in more detail. Thanks for asking.
