Ans: The additional money she earns from dropping her price is known as the marginal revenue.
Explanation:
Marginal revenue refers to the addition made to the total revenue in the subsequent sale of the product.
When Mimi prices her pins at $10, she sells 20 pins per game;
Total revenue = Price * Quantity = $10 * 20 = $200
When she lowers her price to $8, she sells 40 pins;
Total revenue = Price * Quantity = $8 * 40 = $320
Marginal Revenue = Change in total revenue / Change in quantity
= ( $320 -$200) / ( 40 - 20 )
= $120 / 20
= $6
