Vaselesa [24]

Answer:

x ≥ 25

Step-by-step explanation:

In the seventh grade, fifty students are trying for sports supplies to raise at least $2000. They already have $750.

Let us assume that each student has to raise $x more to meet the goal.

Then, a total of 50 students will raise $50x more.

Therefore, the inequality to solve for x will be

750 + 50x ≥ 2000

⇒ 50x ≥ 1250

⇒ x ≥ 25 (Answer)
