d) 5

Respuesta :

Answer:

The correct answer is c) 3.7 .

Explanation:

The first thing we should do is calculate inflation: (2.40 - 2.37) / 2.37 = 1.3

Inflation Rate = 1.3

2.) Calculate the real interest rate

Real interest rate = nominal interest rate - inflation rate

5 - 1.3 = 3.7

3.7 is the real interest rate
