# How many students were in the group initially?

A group of students decide to divide the $400 profit from their book sale among themselves. When they realize that there are three additional students with whom they must split the profits, they once again divide the$400 equally, and each students share of the profits decreases by \$30. How many students were in the group initially?

Please explain how to solve problems like this, as well so that I know how to approach/ do similar ones in the future.
