Question

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

Answer 1

let x = number of comic books she had at the beginning

Answer 2

she starts with x books

then she sells half of them, which means she has x/2 books left over

then she bought 16 more, so you add on 16 to get (x/2) + 16

this is equal to 36 since we're told this

Answer 3

so you need to solve

\[\Large \frac{x}{2} + 16 = 36\]
