Hello there,
The answer will be 15 students.
We will solve the equation as follows:-
First add the total of the students in band and chorus -
β 70 + 95 = 165
Then subtract the previously got number with given number of chorus students:-
β 165 - 150 = 15
So, there are 15 students who are there in both band and chorus.
