Answer: $155,520
Step-by-step explanation:
Pension Expense = Service Cost - Expected return on plan assets + Prior service cost amortization + Interest cost
Interest Cost
= Interest rate * Projected benefit obligation
= 0.09 * 728,000
= $65,520
Pension Expense = 110,000 - 30,000 + 10,000 + 65,520
= $155,520
