Sheila owns a successful hair salon that has many loyal customers. The graph below shows her total weekly sales (in hundreds) over a twelve week period of time.
Which equation below represents the total sales, s, for a given week, w?
A s = 3.2wB s = (1/12)w + 32C s = (1/3.2)wD s = 12w + 3.2

Anticipatory Set
The other day we completed an experiment involving rolling two dice to find what the most frequently occurring sum would be. Today we will find the theoretical probability of each sum occurring.
1.) Based on the Fundamental Counting Principle, how many possible outcomes can there be for rolling two six sided dice?
