The human body converts internal chemical energy into work and heat at rates of 60 to 125W (called the basal metabolic rate). This energy comes from food and is usually measured in kilocalories [1 kcal = 4.186 kJ]. (Note that the nutritional ‘Calorie’ listed on packaged food actually equals 1 kilocalorie). How many kilocalories of food energy does a person with a metoblic rate of 103.0 W require per day? Enter the numerical answer without units.

Show all your calculations.b) The price of a case of ball bearings is $50. Seeing that she can’t make a profit, the chief executive officer (CEO) decides to shut down operations. What are the firm’s profits/losses? Was this a wise decision? Explain. c) Vaguely remembering his introductory Economics course, the chief financial officer tells the CEO, it is better to produce 1 case of ball bearings because marginal revenue equals marginal cost at that quantity. What are the firm’s profits/losses at that level of production? Was this the best decision? Explain. ## Ball Bearings Inc. faces costs of production as follow: Q TFC TVC AFC AVC ATC MC 0$100 $0 1 100 50 2 100 70 3 100 90 4 100 140 5 100 200 6 100 360 a) Complete the above Table by calculating the Company’s Average Fixed Costs (AFC), Average Variable Costs (AVC), Average Total Costs (ATC) and Marginal Cost (MC).
