Answer:
The correct answer is 28.
Step-by-step explanation:
Actually Jada makes problem simpler by adding and subtracting 1
that is
87 ₋ 59 ₋1 ₊ 1
so there would be no effect on our final answer because we have added 1 and also subtracted 1
Now,
87 - 59 -1 + 1
87 - 60 +1 ( ∵ -59 - 1 = -60 )
27 + 1 (∵ 87 - 60 = 27 )
28
so the final answer is 28 .
