Question

Jill sold half of her comic books and then bought sixteen more. She now has 36. With how many did she begun?

Answer 1

36-16=20

20•2=40

Jill started off with 40 comic books

Hope this helps!

Answer 2

Since Jill sold half, you would solve this by multiplying 36 by 2, which would be 64. A way to check this would be to divide your answer, or 62 by 2 (which symbolizes half).
