Dalton, Hunter, and Alex started a Superhero Fan Club. They set a goal to watch as many Superhero movies as they could in one summer. Dalton watched 7 movies, Hunter watched 12, and Alex watched 15. They all watched 2 movies together, but every other movie they watched was different. How many different movies did they see? Let's think first. Chain of thought:
User
Dalton watched 7 – 2 = 5 more movies. Hunter watched 12 – 2 = 10 more movies. Alex watched 15 – 2 = 13 more movies. Altogether, they watched 2 + 5 + 10 + 13 = 30 different movies.
Therefore, the answer is 30.
