Your friend Sharleen is thinking about joining an online gaming club. She's trying to decide between Multiplayer Madness and Games Galore. Her brother insists that Multiplayer Madness is a better deal. Multiplayer Madness charges a joining fee of $50. It's a bit more expensive than Games Galore, a club that charges a $10 joining fee. But, Games Galore charges a fee of $15 a month. That's $5 more a month than the fee charged at Multiplayer Madness!

Sharleen got out her calculator and found that 3 months would cost $80 at Multiplayer Madness, but would cost $55 at Games Galore.

Sharleen is considering joining for either 3 months, 8 months, or 12 months. Will the costs for the two clubs ever be the same? Is one a better deal? Write a summary of the costs for each club and give sharleen advice on which one she should choose. Include a graph with your explanation.
