The amount of money that Li spends on video games depends on how many games he purchases.  If Li has at most $90 to spend on games for his Xbox 360 and the games cost $22.50 each, what is the domain of this function?

• {0 ≤ x ≤ 90}
• {0 ≤ x ≤ 4}
• {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
• {0, 1, 2, 3, 4}

The total cost in dollars to buy uniforms for the players on the volleyball team can be found using the function c = 34.95u + 6.25, where u is the number of uniforms bought.  If there are at least 8 players but not more than 12 players on team, what is the domain of the situation?

• 0 < u ≤ 12
• 0 < c ≤ 425.65
• {8, 9, 10, 11, 12}
• {295.85, 320.80, 355.75, 390.70, 425.65}
