We wanted to study how students at our school spend money.In order to study this,we made some questions to ask our classmates.First,we asked our classmate how much money the spent in one month.Then we asked how much money they spent for things like drinks ,music,books,movies,computer games,and other things.Our math teacher helped us make a graph of our classmates'answers.
Then we thought it would be interesting to compare these answers with our classmates'expenses from last year.It was a little hard for them to remember how much they spent on some things.We used their answers to make another graph for their expenses last year.
Looking at the two graphs,it is easy to compare the axpenses for the two years.Some of their expenses increased,but others decreased.This was a very interesting project for us.
