7. Suppose you own an apartment that you want to let out. You have found a prospective tenant who will pay you $500 per month for the apartment as it is. However, you think that if you invest $2,400 in furnishing the apartment, you might be able to rent it out for $800 per month. Should you offer your apartment to the prospective tenant, or should you furnish the apartment in the hope of higher rents? Explain your reasoning. (2.1)
