Solve clearly

7. Suppose you currently employ three workers and one coffee machine. Are you currently minimizing costs? If not, what changes should you make? [8] 8. If you have increasing returns to scale does this necessarily imply that you have economies of scale? Explain. [8]The wage is $10/br and the coffee machine costs $25/br to purchase and maintain. Draw three isocost curves with a budget of $35, $70, and $105, respectively. [6]
