The highest nominal interest rate he is willing to pay is 8.15%.
The highest nominal interest rate that Juan is willing to pay can be determined using the Fisher equation. The Fisher equation postulates that the nominal interest rate is a function of the real interest rate and the inflation rate.
Fisher effect equation : ( 1 + nominal interest rate) = (1 + real interest rate) x (1 + inflation rate)
(1.03) x (1.05) = ( 1 + nominal interest rate)
( 1 + nominal interest rate) = 1.0815
Nominal interest rate = 1.0815 - 1
Nominal interest rate = 8.15%
