Answer:

48 comic books

Explanation:

Let's use x as the amount that he originally had.

If he sold half of them, that would be:

(1/2)x

Then he bought 8 more, so you would add 8 to that total.

(1/2)x + 8

If he now has 32 then we need to set that equation to equal 32.

(1/2)x + 8 = 32

Subtract 8 from each side.

(1/2)x = 24

Then you will divide 24 by 1/2. That is the same thing as multiplying by 2.

So,

x = 48

Check work

(1/2)x + 8 = 32

(1/2)(48) + 8 = 32

Half of 48 is 24.

24 + 8 = 32.

32 = 32.
