Two competitive retail stores are located next to one another. The demand curve for security services for the first store is \(q_{1}=24-0.5 p_{1}\) and for the second store is \(q_{2}=24-p_{2}\). The marginal cost of security services is \(M C=€ 36\) per hour. Compare the private equilibrium quantity of security services to the social equilibrium quantity of security services.
