A certain high school has 500 students

A certain high school has 500 students. Of these students, 30 are taking music, 20 are taking art, and 10 are taking both music and art. How many students are taking neither music nor art?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
