Answer:
x ≥ 25
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)
