There are 250 students taking either band or chorus. If there are 180 students taking band and 60 students in both mad and chorus, how many students are only in chorus
250-180= 70 because 180 are in band and there are a total of 250 students 70-60= 10 because there were 70 students were left and 60 students were in both and the question wants to know how many students are in chorus ONLY.
