Answer:
x ≤ 72
He needs to sell 72 more bags.
Explanation:
Cho has sold 28 bags and his goal is to sell 100 bags write an inequality to show how many more bags he needs to sell
Let x represent the number of bags he needs to sell
28 + x ≤ 100
x ≤ 100 - 28
x ≤ 72
Therefore he needs to sell 72 more bags.
