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.
To set up a function rule equation, we need to represent the relationship between the total cost and the number of videos ordered.
Let's assume:
- X represents the number of videos ordered.
- C represents the total cost.
For NetBusters:
The sign-up fee is $30.
The cost per video is $1.25.
So, the equation for NetBusters would be:
C(X) = 30 + 1.25X
For BlockFlix:
The sign-up fee is $10.
The cost per video is $2.25.
So, the equation for BlockFlix would be:
C(X) = 10 + 2.25X
To find out when the two services have equal total costs, we can set these two equations equal to each other and solve for X:
30 + 1.25X = 10 + 2.25X
Simplifying the equation:
30 - 10 = 2.25X - 1.25X
20 = 1X
X = 20
Therefore, you would need to order 20 videos for NetBusters and BlockFlix to have equal total costs.
I hope this explanation helps! Let me know if you have any further questions.
