The answer is 40

Start with 40 comic books. Divide in half is 20. Add 16 and you get 36. Try working backwards on these. Like 36-16 is 20...

40 comic books.

Let's say she started with x comic books:

she sold #1/2# of them:

#x/2#

then she bought 16 more:

#x/2 + 16#

now she has 36 comics:

#x/2 + 16 = 36# solve...

#x/2 = 20#

#x=40#
