Ok so this is frustrating me. Can someone help me answer this? What level question would this be? 500? 600? 700?

I cant get this for the life of me.

A city merged two schools. school A and school B merged to have a total of 4500 students after the merge. 10% of the students in school A and 15% of the students in school B were in the marching band prior to the merge. If all the members of the marching back from school A and school B joined together and formed a 570 member marching band, how many students did school A have before the merge?
