3. What factors in to the “price” side of the graph? Chapter 5, Section 2 WHAT ARE THE COSTS OF PRODUCTION?

4. Labor is a cost for producers  Question: Will more labor always = more output?  Short answer – NO  Marginal Cost is the extra cost of producing one more unit.  Marginal product is the change in total output brought about by adding one more worker.  A marginal product schedule shows the relationship between labor and marginal product.

6.  Fixed costs are expenses that the business owner must pay no matter how much or little they produce  Lighting in factory, rent for store, machinery, etc.  These don’t change in the short run  Variable costs depend on the level of production output.  Wages/salaries and raw materials are a good example of this  These do change as production level changes  Total cost is the sum of fixed and variable costs.

8. Where is highest profit? Total product = total revenue/ marginal rev Total cost (fixed and variable costs) = profit – total revenue Marginal cost = Change total cost/ change total product Marginal revenue = price of item Total rev = product x marg cost

9. Practice

10. Equations for the chart  Total product = total revenue/marginal rev  Total cost (fixed and variable costs) = profit – total revenue  Marginal cost = total cost/ total product  Marginal revenue = cost of one unit (price of item)  Total revenue = product x marginal cost
