Barry ate 4 apples and Lewis at x apples. Together they ate 28 total apples.
The number of hours, x, it takes for 4 workers to complete tasks that takes an individual worker 28 hours in total.
Doug gave 4 stickers to each of his 28 friends. He started with x total stickers.
The cost of a video game is $24. Ryan has $4 and Diane has $x.

Answer 1

Only the second situation.

Reasoning:
- 4x = 28 means 4 people each work x hours for a total of 28 worker-hours, so x = 7 hours fits the second scenario.
- 1st: Barry ate 4 and Lewis ate x gives 4 + x = 28 (not 4x = 28).
- 3rd: Doug giving 4 to each of 28 friends gives x = 4·28 (not 4x = 28).
- 4th: Ryan's $4 and Diane's $x totaling $24 gives 4 + x = 24 (not 4x = 28).
