I already know the answers but don't understand how to get them, this is formula: Recovery=insurance carried/insurance required*loss

Ans: 1.) $500 2.) 2500 3.) 25000

Ex.) The replacement cost of Mr. Spears house is $100,000. He bought only $45,000 homeowner insurance for the house with a 90 percent coinsurance clause.

1) $1,000

2) $5,000

3) $50,000
