At the beginning of $2025,$ the pension formula was amended to:

$1\mathrm{.}30\%\backslash$times Service years $\backslash$times Final year's salary

The amendment was made retroactive to apply the increased benefits to prior service years.

Required:

What is the company's prior service cost at the beginning of $2025$ with respect to Davenport after the amendment described above?

What is the service cost for $2025$ with respect to Davenport?

What is the interest cost for $2025$ with respect to Davenport?

Calculate pension expense for $2025$ with respect to Davenport, assuming plan assets attributable to her of $$150,000$ and a rate of return $($actual and expected$)$ of $10\%.$
