Based on efficiency, the businesses that should cut hair are the A and C; moreover, to meet the demand, each firm will need to offer at least two haircuts.
The supply of a product or the units of a product that is offered to potential customers should always meet the number of real customers. In the same way, the price of the product should meet the price customers are willing to pay.
In this context, the best is that only firm A and C cut hair, this is because their prices per cut ($25 and $30) match the consumers' willingness to pay this includes Lorenzo ($35), Gilberto ($50), Juanita ($40) and Neha ($25).
- Firm A can cut Neha's and Lorenzo's hair
- Firm C can cut Gilberto's and Juanita's hair
Moreover, this implies each firm needs to do at least 2 haircuts to cover all the possible customers.
In the case of firms B and D, the price per cut is high ($40 - $45). Based on this, they should not cut hair as only a few customers can pay for this service, and this would be inefficient.
