Answer:
The cost is the same at 10 videos.
Your equations are:
4x
2x + 20
The answer, 10, means that there are 10 videos.
Step-by-step explanation:
First, write out your two equations. It should look like this:
Dreama's Videos: 4x
Membership: 2x + 20
To solve, I keep filling in numbers for x until you get the answer. If you fill in the number 10, for x, you get that it costs $40 for both of them. So, the cost is the same at 10 videos. Your two equations are 4x and 2x + 20. The x represents the number of videos. So, when you get the number 10, it means that there are 10 videos. Hope this helped!
Answer: the rental cost of both members and non members will be the same after x video rentals.
Step-by-step explanation:
Let x represent the number of videos that would be rented for the costs to be the same.
Dreama's Videos charges non members $4 to rent each video. This means that for a non member, the cost of renting x videos is 4x.
If you get a store membership it costs $20 and members only pay $2 to rent a video. This means that as a member, the cost of renting x videos is
2x + 20
For both costs to be the same, it means that
4x = 2x + 20
4x - 2x =>20
2x = 20
x = 20/2
x = 10
