Please Help!! I'm not sure what i'm doing wrong for this problem:
The latest online craze is a new game, Khan on Seven. You get 100 points for playing the game. In addition, you get 50 points for each seven-letter word you are able to make with the ten letters you are given. The game leader currently has 17,950 points. Sal wants to break the record, and needs 18,000 points or more to do so.
Write an inequality to determine how many seven-letter words, w, Sal will need to make to break the record.

If you are on Khan Academy, did you try clicking the "show steps" button?

anonymous · Answer

did you

yes I am on khan academy, I have to get 3 correct in a row, and if i click the "show steps" button it will automatically count my answer as wrong :/

Yea, I just checked your work and it looks correct. You should check the steps despite the being counted as wrong, because sometimes it glitches. If you have the right answer, and it still won't except it, you will need to report it.
