Trip wanted to watch the new action movie in theaters.  An evening ticket cost $10 and a large popcorn & drink combo would cost him an additional $10.  He noticed on their website, they had a special offer.  From 12 noon to 3 pm, save 20% off tickets and 50% off any food combos.  How much money could Trip save by going to the earlier movie?
