Answer:
is $4.67
Step-by-step explanation:
Marginal revenue of a company selling a product is the extra revenue realised from the sale of extra units of the product.
For example if 1 unit of a pen is sold at $5, the marginal revenue is 5/1= 5.
Also when 10 units are sold at $50, marginal revenue is 50/10= 5.
So for extra sales of product Z the marginal revenue is $4.67 showing that is the price per unit of Z, and it is constant.
