SCENARIO 14-20-A
You are the CEO of a dairy company. You are planning to expand milk production by purchasing
additional cows, lands and hiring more workers. From the existing 50 farms owned by the company,
you have collected data on total milk production (in liters), the number of milking cows, land size (in
acres) and the number of laborers. The data are shown below and also available in the Excel file
