Answer:
It depends on the agreement she has with the insurance company.
Explanation:
At first the company made her to believe that they would cover the expenses. The statement by the company explains that they must have carried out a research or made enquiry about the cost but didn't conduct a research on whose fault it was as a result of the accident.
On stating in the paper that Shelly signed that they would only fit the bill of 30% for the medical, shows that this time,they had made there research and arrived at the conclusion to only pay 30%. Maybe they have seen the medical report and also had contacted agencies responsible to examine the accident.
Based on these facts,( the 30% they are to fit the bill) it is can be concluded that the insurance company carried out a research on the cause of the accident and concluded that Shelly is the actual cause of the accident but are ready to pay 30% of the medical bills, this must have been part of the agreement between Shelly and the insurance company.
