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?
An evening movie is $10 and the food combo would be $10 so 10 + 10 = $<<10+10=20>>20
If he goes to an earlier movie, it's 20% off the normal ticket price of $10 so 10 * .20 = $<<10*.20=2>>2
If he goes to an earlier movie, it's 50% off the normal food price of $10 so 10 * .50 = $<<10*.50=5>>5
If he saves $2 for the ticket and $5 on food, then 2+5 = $<<2+5=7>>7 saved
