I just need help understanding this one question.

A store rented 6,816 movies in April. This was 40% less than the number of movies it rented in March. The following equation represents this situation, where m represents the number of movies the store rented in March.
m - 0.4m = 6,816
How many movies did the store rent in the two months combined?
