Please help..

Last year, Eleanor and Felix Knight bought a home with a dwelling replacement value of $350,000 and insured it (via an HO-5 policy) for $310,000. The policy reimburses for actual cash value and has a $500 deductible, standard limits for coverage C items, and no scheduled property. Recently, burglars broke into the house and stole a 2-year-old television set with a current replacement value of $600 and an estimated useful life of 8 years. They also took jewelry valued at $1,850 and silver flatware valued at $3,000.

1. If the Knights' policy has an 80 percent co-insurance clause, do they have enough insurance?

2. Assuming a 50 percent coverage C limit, calculate how much the Knights would receive if they filed a claim for the stolen items.

3. What advice would you give the Knights about their homeowner's coverage?
