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 make with the ten letters you receive. Sal wants to break the record, and he needs 18,000 or more points to do so. Write an inequality to determine the number of seven-letter words, w, Sal could make to break the record.

I know the inequality is 50w + 100 >_ 18000 but it also says to graph the solution set to this inequality.
