• above types of goods,explain and evaluate the actions you would take to increase the revenue earned from sale of each type of good.

• Answer:

  I'm not particularly sure of your classifications other than complementary, but I'll try to help you out. increase in sales of complementary goods should occur with an increase in sales of "normal" goods. Inferior goods would seen almost entirely price sensitive....you can increase revenues by decreasing costs/sales price.
