We attempted the Alisons cinema problem. We started with the example- 5 adults,20 pensioners and 75 children. After adding up these amounts we found that even though we had 100 people the profit was too high so we took away an adult and added a child so that we still had 100 people but we were getting closer to the answer. We kept on doing this until we got an answer but every time we took awat or added a person we made sure that we added or took away another person so that when we did find an answer we did also have 100 people.
