Answer: the greatest number of helium balloons that you can buy is 25
Explanation:
You are in charge of purchasing helium balloons for a school carnival.
Let x represent the number of helium balloons that you purchased for the school carnival.
You have been given $40 to buy the balloons. The balloons cost $1.60 each. Therefore, an inequality representing the greatest number of helium balloons that you can buy would be
1.6x ≤ 40
x ≤ 40/1.6
x ≤ 25
