Answer:
is there picture?
Step-by-step explanation:

bear in mind that the continuously compounding interest is just that, a daily compounding cycle, taking a year as 365days.
The Gcf is finding the greatest numbers the lcm is finding the least factor
and the are the same because your finding the common number> (means same number)
700, because 8 is 5 and up so it'll be rounded up.
Each question is worth 4 points (100/25=4)
Therefore, when you divide 83 by 4, you get 20.75, as as he's aiming to get a B, this needs to be rounded up to 21.
Xio would need to get 21 questions right to get a B, hope this helps :)
