Answer:
Each snack cost $3.75.
Explanation:
Javier and his two friends paid 6 bucks for their tickets in total.
If all together they spent 17.25 at the game, we can deduct 6 dollars from 17.25 so we can just get the snack total.
17.25-6=11.25
Since there are three people, and they bought 3 snacks, we can divide:
11.25/3=3.75
Each snack cost $3.75
