Answer:
Susan has more books than Michael.
Step-by-step explanation:
If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60
40 + 8 = 48
60 is more than 48, so Susan has more books than Michael
64/3=x/1

64/3=21 and 1/3 calls per hour
4

This is because there is an imaginary 1 in front of the first sqrt.
I’m pretty sure it’s B. But I could be wrong.
