b. What are two equations that model the data? (The sales become much greater between 10 and 12 months, so this is probably when the second store opened. Use the DreamCalc calculator to make a best fit line to model the data from 0 to 10 months. Use the DreamCalc calculator to make a second best fit line to model the data from 12 to 20 months. Write the equations for the lines.) What are the domain and range of each equation? Explain your process.
