Please can someone tell me the excel formula to help calculate this because I have more of questions and I can't post all the questions here because there too many.

Imprudential, Inc., has an unfunded pension liability of $760 million that must be paid in 25 years. To assess the value of the firm's stock, financial analysts want to discount this liability back to the present.

If the relevant discount rate is 8 percent, what is the present value of this liability? (Do not round intermediate calculations and enter your answer in dollars, not millions of dollars, rounded to 2 decimal places, e.g., 1,234,567.89.)
