It’s c for sure only because I had it on a test
I think that it would produce a circle i'm not sure though. do you have a picture to go along with it?
Y=-2
You combine like terms which would be -14 and 22. 22-14=8. Then you subtract that from 0. 0-8=-8. Then divide -8 by 4y. -8÷4=-2
The answer is $12.5 for 10 bottles
