Answer 1

3 boxes will be left after 3 hours.

Explanation:

The gift shop is having a sale. your friend sells half her stock of key rings every hour.

She has 24 boxes at the start of the sale.

Means after 1 hour she will have =
`(24)/(2)=12` boxes left

After 2 hours, she, will have =
`(12)/(2)=6` boxes left

And after 3 hours, she will have =
`(6)/(2)=3` boxes left

Therefore, the answer is : 3 boxes will be left after 3 hours.

Answer 2

To solve for the given problem above:

Let x be the number of boxes left after 3 hours

3 * ½ X = 24

3/2 X = 24

X = 24 * 2/3

X = 16

The correct answer is 16.
