C

Step-by-step explanation:

First, examine the information given

Snap is 12 FEWER than 3 TIMES the number of posts on insta, so:

s = 3i -12

Snap and insta COMBINED is 256 posts, so:

s + i = 256

So what we got now is:

s = 3i - 12

s + i = 256

Unfortunately, this is not one of the answers, but that's okay.

If you look at C, it says s = 256 - i. This is equivalent to s + i = 256.

So the answer is C
