Answer: C. $120+x\ge240$

Explanation:1. Understand the components of the situation: - Goal amount: at least $ $240$ . "At least" means greater than or equal to ( $\ge$ ). - Amount already saved: $ $120$ . - Additional amount needed: x dollars.

Formulate the total amount Sabrina will have after saving the additional amount: Total amount saved = Amount already saved + Additional amount needed Total amount saved = $120 + x$ .
Set up the inequality based on the goal: Sabrina wants the total amount saved to be at least $ $240$ . So, Total amount saved $\ge 240$ . Substituting the expression for the total amount saved: $120 + x \ge 240$ .
Check the solution with the options: The inequality we derived is $120 + x \ge 240$ . This matches option [C].
Conclusion: The inequality that represents this situation is $120+x\ge240$ .
