Calvin took his friends to a movie for his birthday. The movie tickets cost $12 per person. He spent less than $180. If x is the number of friends he took along, then the inequality that represents the situation is 12x≤180 180x ≥12 x+12≤180 12+x≥180 . Calvin took at most friends to the movie. 13 14 15 16
