Question

marcus wants to save at least $350 to buy a new laptop. he already has $120 saved. which inequality can be used to find x, the amount of money marcus still needs to save? \\(\boldsymbol{x + 120 \geq 350}\\) \\(\boldsymbol{120 + x \leq 350}\\) \\(\boldsymbol{x + 120 < 350}\\) \\(\boldsymbol{120 + 350 \geq x}\\)

Explanation:

Step1: Analyze the problem

Marcus already has $120 and needs to save $x more. He wants to save at least $350, which means the total amount he has (saved + still needs to save) should be greater than or equal to $350.

Step2: Form the inequality

The total amount is $x + 120$ (or $120 + x$), and it needs to be at least 350, so the inequality is $x + 120 \geq 350$.

Answer:

A. \( x + 120 \geq 350 \)
