Assume a new business rule is added:

It has been noticed that the previous rules do not have a case for clients above the age of 85, which is a problem, as some people live to be over 85.

Adjust the application to reflect the following: Client's above 85 should see

• a $5 premium increase, no warning letter, and no policy cancellation at 0 claims
• a $25 premium increase, no warning letter, and no cancellation at 1 claim
• a $100 premium increase, warning letter type 4, and no cancellation at 2-4 claims
• a $0 premium increase, no warning letter, and policy cancellation at 5 claims

Do this by first adding new, failing unit tests for these conditions, then adjusting the application to make them pass
