Final answer:
Monique needs to practice for at least 4 days per week to achieve her goal of practicing for a minimum of 6 hours per week.
Step-by-step explanation:
To determine the number of days Monique needs to practice in order to achieve at least 6 hours of practice per week, we can formulate and solve the following inequality: 1.5x ≥ 6, where x represents the number of days she practices per week.
We can solve the inequality by dividing both sides by 1.5: x ≥ 4.
Therefore, Monique needs to practice for at least 4 days per week to achieve her goal of practicing for a minimum of 6 hours per week.
