Suppose you want to join a video store. Big Video offers a special discount card that costs $9.99 for one year. With the discount card, each video rental costs $2.49. A discount card from Main Street Video costs $20.49 for one year. With the Main Street Video discount card, each video rental costs $1.79. After how many video rentals is the cost the same?

**carpediem**, Wednesday, April 1, 2009 at 9:47pmCost of x videos from Big Video:

9.99 + 2.49x

Cost of x videos from Main Street Video:

20.49 + 1.79x

Set the two equations equal to each other to find when the cost will be the same:

9.99 + 2.49x = 20.49 + 1.79x

10.5 = .7x

x = 15 videos
