I've tried to solve this problem 3 different times and can't get it right. It's due on April 2nd, please help!

Sachs Brands's defined benefit pension plan specifies annual retirement benefits equal to 1.2% service years final year's salary, payable at the end of each year. Angela Davenport was hired by Sachs at the beginning of 2010 and is expected to retire at the end of 2044 after 35 years' service. Her retirement is expected to span 18 years. Davenport's salary is $85,000 at the end of 2024 and the company's actuary projects her salary to be $255,000 at retirement. The actuary's discount rate is 7%. Note: Use tables, Excel, or a financial calculator. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1)

Required: 2. Estimate by the projected benefits approach the amount of Davenport's annual retirement payments earned as of the end of 2024.

3. What is the company's projected benefit obligation at the end of 2024 with respect to Davenport? Note: Do not round intermediate calculations. Round your final answer to the nearest whole dollar.

4. If no estimates are changed in the meantime, what will be the company's projected benefit obligation at the end of 2027 (three years later) with respect to Davenport? Note: Do not round intermediate calculations. Round your final answer to the nearest whole dollar.
