Answer
The increase in the annual rate to 6000 dollars will maybe increase profit in the first, but as time goes by, fewer people will buy the insurance.
The number of people who buy insurance will be less as compared to the previous one.
Also, Since it's more expensive or costly as compared to before, those with health problems will be in the majority.
So, the firm's pool of customers tends to be more unhealthy.
That will lead to a greater death rate and larger costs for the insurance company.
However , the company's profit won't necessarily increase.
