Responses
A 0.25x + 3 < 10; 28 games0.25x + 3 < 10; 28 games
B 0.25x + 3 ≤ 10; 28 games0.25x + 3 ≤ 10; 28 games
C 0.25x - 3 < 10; 52 games0.25x - 3 < 10; 52 games
D 0.25x - 3 ≤ 10; 52 games0.25x - 3 ≤ 10; 52 games

Answer 1

Cost: 3 + 0.25x ≤ 10. So 0.25x ≤ 7 ⇒ x ≤ 28. Maximum whole number of games = 28.

Answer: B.
