Nocturna Mattress Ltd kept a large inventory of beds in its warehouse. As a matter of internal management, it tried to keep about $60 000 worth of stock on hand at all times. It purchased property insurance from Citadel Insurance. That policy contained a co-insurance clause that called for the insured to hold 80 percent coverage. Nocturna nevertheless chose to pay for only $30 000 worth of coverage. As a result of a cycle of heavy snowfall and warm weather, Nocturna's warehouse was flooded, and much of its inventory sustained irreparable water damage. It therefore has made a claim under its policy with Citadel. How much will Nocturna receive if (i) the total loss was valued at $50 000, (ii) the total loss was valued at $40 000, and (iii) the total loss was valued at $30 000 and the policy also contained a $5000 deductible? Explain your answers.
