There are 250 students taking either band or chorus. If there are 180 students taking band and 60 students in both band and chorus, how many students are in just chorus?

band + chorus + both = 250
(180 - 60) + chorus + 60 = 250
120 + c + 60 = 250
180 + c = 250
c = 250 - 180
c = 70

check..
band + chorus + both = 250
120 + 70 + 60 = 250
250 = 250 (correct)

so there is 70 in just chorus
