Levon has 45 minutes until he needs to leave for his piano lesson. He spends 27 minutes watching an episode of his favorite TV show. Then he wants to play a game on his tablet. At most, how long can Levon spend playing the game before he need to leave?

Solve the inequality.

1 answer

45 - 27 - x ≤ 0
18 - x ≤ 0
-x ≤ -18
x ≥ 18

Therefore, Levon can play the game for at most 18 minutes before he needs to leave.
