William sold half of his comic book collection then purchased 10 more. He now has 24 comic books . How many books did William begin with?

28

Step-by-step explanation:

24-10=14

14x2=28

willaim had 28 comic books to begin with

Step-by-step explanation:

So we can take 24-10=  to see how many comics he had before his total of 24  which :

24-10=14

Then we want to find how many he had in the beging so to reverse division we would use multiplication so we would do 14x2=  because a half x a half will equal a whole :

14x2=28

So therefor William started of with 28 comic books

i believe the correct answer is b.
