If John is at fault, he must pay the deductible amount of $100 himself.
As given,
John has an automobile medical payments insurance in the amount of $1,000. So, he will get $1000 complete for his medical bills by the insurance company. Also, he has done $900 worth of damage to Sam's car, but the company will pay him $800 for this.
Hence, total amount becomes = 1000+800 = $1800
So, the insurance company will pay John a sum of $1800.
