An airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21 point 2 pounds. The inequality represents the amount of weight Lorrie can add to the carry-on without going over the 30 -pound limit. 21 point 2 plus w is less than or equal to 30 How much weight can Lorrie add to the carry-on without going over the 30 -pound limit?
Answer
A
no less than 8 point 8 pounds
B
more than 8 point 8 pounds
C
no more than 8 point 8 pounds
D
less than 8 point 8 pounds
Explanation
Subtract 21.2 from both sides of the inequality: w ≤ 30 − 21.2 = 8.8. So Lorrie can add no more than 8.8 pounds without exceeding the limit; exactly 8.8 pounds brings the bag to 30 pounds.
