A beer distribution company compiled information on the behavior of craft beer sales for the past year. The record of sales in thousands of cases per month for three of their beers is presented below. We'll call them Beer A, Beer B, and Beer C.

For next year, a 15% increase in total beer sales is expected compared to this year. Here are the instructions for data analysis.
