The Harrison Group Life Insurance company computes annual policy premiums based on the age the customer turns in the current calendar year. The premium is computed by taking the decade of the customers age, adding 15 to it, and multiplying by 20. For example, a 34 year old would pay $360, which is calculated by adding the decades (3) to 15, and then multiplying by 20. Write an application that prompts a user for the current year and a birth year. Pass both to a method that calculates and returns the premium amount, and then display the returned amount.
