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

Question

texaschic101 · Answer

let x be the # of video rentals
9.99 + 2.49x = 20.49 + 1.79x

now just solve for x and you will find your answer.

Can you do that, or do you still need help ?

if you do not want to deal with the decimals in the problem, just multiply the entire equation by 100 and then solve for x
