The answer would be $414,473.68.
Replacement cost of $950,000 X 80% coinsurance = $760,000 so Daniel would have had to carry $760,000 in order to meet the coinsurance requirement. Since he carried $60,000 less than the coinsurance requirement, he was underinsured and would have to suffer a coinsurance penalty on the $450,000 loss. The penalty is calculated is calculated as follows:
$700,000 over $760,000 = .921052631 times $450,000 = $414,473.68 so the coinsurance penalty would be $35,526.32 (before whatever policy deductible there is is subtracted from the loss payment).
Hope this helps!
