Answer:
The insurance company will pay a maximum of $20,000.
Step-by-step explanation:
10/20 represent the highest monetary amount that Sarah's insurance company will pay if someone is injured.
Now, here 2 persons are injured but the top limit is $20,000, so the insurance company will pay $20,000 only.
Arthur's medical expenses total $16,000, Fred's come to $8,000. Totaling to $24,000 but the limit is $20,000.
So, $4000 will be paid by Sarah and $20,000 by the insurance company.
