Answer:
passing all classes - no tutoring: 115
not passing - total: 280
total for all: 210, 315, 525
Explanation:
to get the no tutoring one you subtract the attending tutoring from the total (245 - 130) which gets you the 115.
for the total in the second row down you just add up the two numbers given (80 + 200) to get 280.
then from there you just add down (130 + 80), (115 + 200), (245 + 280), which gets you in order 210, 315, 525.
hopefully this helps
