Melanie is a hairdresser and is able to provide haircuts for 8 people each day at a total cost of $50. If Melanie performed 9 haircuts it would cost her $60. What is the marginal cost of providing the 9th haircut?
To solve this problem, we first need to understand what marginal cost is and then figure out how to calculate it. Marginal cost is the additional cost to a firm of producing one more unit of a good or service. In this case, the problem is asking for the marginal cost of going from 8 haircuts to 9 haircuts. To calculate the marginal cost you take the cost of 9 haircuts and subtract the cost of providing 8 haircuts.
$60 - $50 = $10.
The marginal cost of providing the 9th haircut is $10.
