Sagot :
Answer:
4 students take both Economics and Government.
Step-by-step explanation:
Total number of students in the class: 50
Students who offer Economics: 30
Students who offer Government: 17
Students who offer neither Economics nor Government: 7
find out how many students offer at least one of the subjects (Economics or Government). subtract the number of students who offer neither subject from the total number of students: 50 - 7 = 43
Students taking at least one subject = (Students taking Economics) + (Students taking Government) - (Students taking both)
43 (at least one) = 30 (Economics) + 17 (Government) - Both
43 = 47 - Both
Both = 47 - 43
Both = 4
