kira will spend less than 27 on gifts. so far, she has spent 12$. what are the possible additional amounts she will spend?

The key word in this problem is less than. So we know this is an inequality.

Let s be Kira's possible spend. We have:
s + 12 < 27

To solve for s in this inequality, we subtract 12 from each side:
s + 12 - 12 < 27 - 12

Cancel the 12's on the left side, and we get:
s < 15

The summary here is Kira can spend anything up to but not including 15
