• 800 + 25x < 1280 - 15x

A hockey season ticket holder pays $72.48 for all of her tickets plus $6 for a program each game. A second person pays $18.08 for a ticket to each game, but doesn’t buy programs.  Write an equation that shows when the two fans will pay the same amount.
In how many games will they have paid the same amount? 

• 18.08 + 6x = 72.48x;  6 games
• 72.48 + 6x = 18.08; 9 games
• 72.48 + 6x = 18.08x; 9 games
• 72.48 + 6x = 18.08x; 6 games
