Marginal Revenue
If a firm can sell all it wishes without having any effect on market price, marginal revenue will be equal to price
If a firm faces a downward-sloping demand curve, more output can only be sold if the firm reduces the good’s price

Suppose that the demand curve for a sub sandwich is
q = 100 – 10p
Solving for price, we get
p = -q/10 + 10
This means that total revenue is
R = pq = -q2/10 + 10q
Marginal revenue will be given by
MR = dR/dq = -q/5 + 10
