You are liable to pay = $42,000 plus $20,000 plus $1,500 plus $25 = $63,525
Step-by-step explanation:
Amount Covered by Insurance
Medical bill upto $30,000 per person, upto a total of $60,000 for all passengers.
P1 = $25,000
P2 = $2,000
P3 = $5,000
P4 = $28,000 [Rest $42,000 for passenger 4 would come out of your pocket as the liabilities ($70,000) exceed the limit of $30,000]
$25,000 plus $2,000 plus $5,000 plus $28,000 = $60,000
Property Damage: Property damage limit is $40,000 hence, rest $20,000 will come out of your pocket.
Liability insurance doesn't pay to repair or replace your car or to treat your injuries. Hence, $1,500 worth of damage and your medical bills of $25 will be borne by you too.
Insurance Company is liable to pay = $60,000 plus $40,000 = $100,000
You are liable to pay = $42,000 plus $20,000 plus $1,500 plus $25 = $63,525
