Answer:
Maximum of 11
Explanation:
Considering Julie has 2.75 yards of ribbon and each pillow requites 0.25 yards, you can use the inequality 0.25x ≤ 2.75 since she can use a maximum of 2.75 yards of ribbon.
To solve 0.25x ≤ 2.75, you would first divide both sides by the coefficient, 0.25, to give you x ≤ 11.
x ≤ 11 means that Julia can make a maximum of 11 pillows.
