The library was hosting a​ book-signing event for a popular author of​ children's books. It advertised a free juice box and small bag of pretzels for all children who attended the event. The librarian anticipated that no more than 200 children would attend the​ event, but 257 children showed up. Use this information to answer parts 14. 1. The librarian had purchased 200 juice boxes for​ $136. She sends Pat and Chris to the store to buy juice boxes for the extra children. If they find juice boxes for the same unit​ price, how much will they spend on the additional juice​ boxes?
