Question

Samuel played a video game. He gained some points, lost 87 points, and finished with less than 320 points. Which of the following inequality represents the given situation?

Answer 1

From the problem, Samuel gained some points, let that points be equal to n

then lost 87 points

So from what he gained, subtracted by 87 points, his actual points will be :

n - 87

Then he finished with less than 320 points

So it follows that :

`n-87<320`

The answer is n - 87 < 320
