12.WA30.7.3 profit or loss.
12.WA30.7.a Analyze small businesses such as a hot dog stand to identify and describe expenses, and explain factors, such as seasonal variations and hours of operation that might impact their profitability.
12.WA30.7.b Research and describe feasible small business options for a given community.
12.WA30.7.c Analyze a small business to generate options that might improve its profitability, and report to an audience.

12.WA30.9.g Explain, using examples such as course marks, why some data in a set would be given a greater weighting in determining the mean.
12.WA30.9.h Calculate the mean of a set of numbers after allowing the data to have different weightings (weighted mean) and explain the reasoning.
12.WA30.9.i Explain, using examples from print and other media, how and why measures of central tendency and outliers are used to provide different interpretations of data.
12.WA30.9.j Create and solve situational questions that involve measures of central tendency.
