Sam sold half of his comic books and then brought seven more. He now has twelve. how many did he began with?
Please show work and answer.

Sagot :

Answer:

He began with 10 comic books

Step-by-step explanation:

12 - 7 - 10 comic books he started out with

10 ÷ 2 = 5

5 left after he sold half of his comic books

5 + 7 = 12 comic books after he brought seven more

Hope this helps!
He began with 10 books
12-7=5
And the story problem says “he sold half” so then 5 x 2 = 10 (you got the five from dividing the 10 by 2)
