To celebrate the New Year, a principal orders 100 chocolate bars to give to her students. When the chocolate bars arrive, she realises the chocolate bars have a special offer. If you hand in 10 wrappers, you receive a free chocolate bar!
If everyone in the school saves their wrappers, how many chocolate bars can the school get?
