Question

An airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21.2 pounds. The inequality represents the amount of weight Lorrie can add to the carry-on without going over the 30-pound limit.
21.2 + w<(With a line underneath it) 30

How much weight can Lorrie add to the carry-on without going over the 30-pound limit?
less than 8.8 pounds
more than 8.8 pounds
no less than 8.8 pounds
no more than 8.8 pounds

Answer 1

To solve this you subtract 21.2 from 30.
30 - 21.2 = 8.8.

If she goes over 8.8, her bag will weigh more than 30 pounds. So the answer is: no more than 8.8 pounds. 

Answer 2

Answer:

Option D:No more than 8.8 pounds.

Step-by-step explanation:

We are given that an airline charges an extra fee if a carry bag weighs more than 30 pounds.

Lorrie's carry weighs= 21.2 pounds

We are  given the inequality that represents amount of weight Lorrie can add without going over the 30- pound limit.

$21.2+w\leq30$

We have to find how much weight Lorrie can add to the carry on-without going over the 30

By solving inequality we find the value of w

Subtract 21.2 from both sides of inequality

$21.2+w-21.2\leq 30-21.2$

$w\leq8.8$

Therefore, Lorrie can add  weight less than or equal to 8.8 pounds.

Hence, option D  is true.
