Add 3 on both sides: 2I5-2xI≤18
divide 2 on both sides: I5-2xI≤9
-9≤5-2x≤9
subtract 5: -14≤-2x≤4
divide by -2. Remember: when divided by a negative number, the inequality symbol changes direction. so we have7 ≥x≥-2
rewrite it: -2≤x≤7
so the answer is C
you were right.

<h2>There were 280 people in total.</h2>
Step-by-step explanation:
The total cost is $560, according to the problem. We also know that the cost per person is $2. So, to find the number of people, we just need to divide
