Hi there! The answer is A. Add together 200 and 100. Then divide the sum by 6.
In this problem we want to know how many books there are on 1 shelf. Therefore we must first now the total amount of books and so we add up 200 and 100 (which makes a total of 300 books)
Finally we divide this total amount of books by the amount of shelfs (300 / 6), and then we've found the answer to our question. Hence, the answer is A.

Answer:
200
Step-by-step explanation:
If the theater sold 8 more popcorns, the total would be 600, and it would be exactly 3 times the number of hotdogs. The theater sold 1/3 of 600, or 200 hotdogs.
X^2-12+36=90
(x-6)^2=90
x-6= sqrt of 90
x-6= +- 3 sqrt of 10
x = 6 +- 3 sqrt of 10
