I think the answer is 7.00%. Base on my research, to get the nominal rate you need to have the real rate and inflation. So in this problem, the given are the following: the inflation rate is 3.00%; the real rate is given by -1 where FV = 26, PV = 25 and n = 1. The real rate -1 = 0.04 or 4.00%.
Formula Nominal rate= real rate + inflation
= 4.00% + 3.00%
= 7.00%
7.00% is which the rate needed to compensate for her to wait and to cover inflation
