document.write( "Question 1195188: A public relations $\"highlight%28cross%28exert%29%29\"$ expert developed the model P(x)=0.5x+15 to predict a political candidate's performance in a certain upcoming election based on the amount the candidate spent on advertising in the model, P(x) is the percentage of votes, and x is the number of dollars, in thousands, spent on advertising. For example, if a candidate spends $0 on advertising, the model predicts that the candidate will receive 15% of the votes. Based on the model if a candidate receives 40% of the votes in the election, how much did the candidate spend on advertising?
