Okay, good. So you have $1.92 per box So your equation that you would put down would be...?

Oh, wait. I'm sorry. Hold on. I got this wrong. I hope you aren't mad. Let me re read the question.

Okay. I got it. I know how to do this question now.

The equation would be 16/12 because there are twelve boxes and all of them added up together would be 16. So you would write your equation like this: 16/12 = 1.33... and so on.
