Answer:
76
Explanation:
so the first bit you don't even need its trying to trick you
first you do 72/6= 12 so that means for every 12 students, you need one tutor
then you do 120-72=48 and that means there are 48 students that have no tutor
to find out how much more tutors you need, do 48÷12= 4, meaning you need 4 extra tutors for the 48 more kids.
last you add 72 witch is the about of tutors you started with, to 4 witch is how much you just got.
72+4=76
