Erica works in a soda-bottling factory. As bottles pass her on a conveyer belt, she puts caps on them. Unfortunately, Erica sometimes breaks a bottle before she can cap it. She gets paid 4 cents for each bottle she successfully caps, but her boss deducts 2 cents from her pay for each bottle she breaks.

Erica is having a bad morning. Fifteen bottles have come her way, but she has been breaking some and has only earned 6 cents so far today. How many bottles has Erica capped and how many has she broken?
