Question

Mike sold 1/2 of his comic book collection. He then bought 8 more. He now has 18 comic books. How many did he begin with? Help :(

Answer 1

Answer:

20

Step-by-step explanation:

18 minus the amount of comic books he just bought (8)

Thats 10. If he sold half of his comic books that means he had twice that of 10

10x2=20
