To find the total number of comic books Sophia and Jacob have, you can use the equation:

c = 8 (Sophia's comic books) + j (Jacob's comic books)

Now, we know that Jacob has 2 times as many comic books as Sophia, so:

j = 2 * 8 (Sophia's comic books)

j = 16

Now, you can substitute the value of j into the first equation:

c = 8 + 16

c = 24

So, Sophia and Jacob have a total of 24 comic books in all. The equation you can use to find this is:

c = 8 + 2 * 8
