The Stack has just written and recorded the single greatest rock song ever mad

The Stack has just written and recorded the single greatest rock song ever made. The boys in the band believe that the royalties from this
song will pay the band a handsome $250000 every year (at the end of the year) forever. The record studio is also convinced that the song will be a smash hit
and that the royalty estimate is accurate. The record studio wants to pay the band up front and not make any more payments for the song. What should the record
company offer the band if it uses a 5.5% discount rate a 7.5% discount rate or a 10.5% discount rate?
