marginal revenue[/B] (R') is the additional revenue that will be generated by increasing product sales by one unit
The Attempt at a Solution
I don't know how to start. Q is the number of items sold at price x. y is the marginal cost, the cost of producing one item. N is the net profit, the revenue (my english isn't perfect so i explain each variable) ##~N=Q(x-y)~##.
The derivative N' is the marginal revenue, no?
Q, x and y are variables. x and y can change according to Q, because if i produce more i can lower the price i charge (x) and also the cost y.
How do i express marginal revenue?
