Editing Marginal revenue (section)

==Marginal revenue and Marginal benefit==
'''Example 1:''' Suppose consumers want to buy an additional lipstick. If the consumer is willing to pay $50 for this extra lipstick, the marginal income of the purchase is $50. However, the more lipsticks consumers have, the less they pay for the next lipstick. This is because as consumers accumulate more and more lipsticks, the benefits of having an additional lipstick will be reduced.

'''Example 2:'''  Suppose customers are considering buying 10 computers. If the marginal income of the 11th computer is $2, and the computer company is willing to sell the 11th component to maximize its consumer interest, the company's marginal income is $2 and consumers' marginal income is $2.
