1.8 The Barbers is a midlevel hair salon that has some market power. Suppose that the managers of The Barbers have set prices for a basic haircut of

$20 for an adult and $10 for a child. The marginal cost of both types of haircuts are equal. The managers discover that the marginal revenue from an adult haircut is $16 and the marginal revenue from a child haircut is $8. To maximize their profit, should these managers change the prices of the adult and child haircuts? Why or why not?
