Hello, this is a practice problem for a class I'm struggling with. The professor isn't much help, I'd really appreciate if someone here can answer this and break it down so I can follow the logic and see where I'm going wrong with these problems.

The XYZ corporation pension plan provides a lifetime annual income to its employees upon retirement at age 65. The plan provides 3% for each year of service of the employee's salary upon retirement. Moreover, those retiring after 65 have their benet increased by 1.8% for each year beyond 65 that they work. Caitlin retires at age 73 with 19 years of service. If her salary upon retirement is $55,242, what is her annual pension benet? Round your answer to the nearest dollar
