Answer:
5.37%
Explanation:
Real rate of return = [tex]\frac{1 + NominalRate}{1 + InflationRate} -1[/tex]
= [tex]\frac{1+0.08}{1+0.025} - 1[/tex]
= 0.053658 or 5.37%
The cousin loaned $420 to Becka
she would expect Becka to pay back 420 x (1 + 5.37%) which is equal to $442.554
The real return on the loan = [tex]\frac{442.55-420}{420}[/tex] × 100 = 5.37%
