Write an inequality to represent this real-world situation. Andre wants to practice the piano 9 hours a week. Each time he practices he practices for 23 hour. If he has already practiced 2 hours this week, how many sessions, x , does he still need to practice to reach or surpass his goal
Let x be the number of sessions Andre still needs to practice to reach his goal of practicing 9 hours a week.
Since each session is 2 hours long, the total number of hours Andre needs to practice to reach his goal is:
2x
And the inequality representing this situation is:
2x + 2 ≥ 9
Solving for x:
2x ≥ 7
x ≥ 3.5
Therefore, Andre still needs to practice at least 4 more sessions to reach his goal.
