Question

Beth sold half of her comic books and then bought nine more. She now has 28. How many did she begin with?

Answer 1

38 because if you subtract 9 from 28 it becomes 19 and then all youd need to do is add another 19 that makes 38

Answer 2

28 - 9 = 19
19 + 19 = 38
she started with 38 comics
