Answer:
Step-by-step explanation:
Lets say,
C= 35 A=28 B= 20
How to get math,
C- A= m
35 -28= 7
How to get science,
C-b=s
35 -20 = 15
How to get both,
The answer of math is 7 and the answer for math is 15. Add it so it'll become 22, then subtract the no. Of student who join the online class to then sum of 15 &7 which us 22. So ganito sya.
35-22= 13
So the no. Of student who join both club is 13
