Fifteen times a number is at most seventy-two. Write an inequality to represent this statement. Then, solve the inequality. (1 point)
1. An inequality is 15x = 72 The solution is x = 4.8.
2. An inequality is 15x ≥ 72 The solution is x ≥ 4.8
3. An inequality is 15x ≤ 72 The solution is x ≤ 4.8
4. An inequality is 15x > 72 The solution is x > 4.8
3. An inequality is 15x ≤ 72
The solution is x ≤ 4.8.
