Question

16) Jill sold half of her comic books and then bought

sixteen more. She now has 53. How many did she
have to begin with?

Answer 1

74

Explanation:

16-53 is how many she had before she bought some which is 37 and she said she sold half so that means she had 74 to begin with, so starting with 74 you then sell half which puts you down to 37 add 16 new ones and you have 53. Hope this helps!

Answer 2

the answer is 90 because 53 times 2 is 106 and if you subtract 16 you have 90
