Answer:

Nominal interest rate (n) = 10% = 0.10

Inflation rate (i) = -2% = -0.02  

Real interest rate (r) = ?  

Application of Fisher's Equation                                                      

(I + n) =   (1 + r)(1 + i)

(1 + 0.10)  = (1 + r)(1 + -0.02)

1.10 = (1 + r)(0.98)

1.10 = 1 + r

0.98

1.1224 = 1 + r

1.1224 - 1 = r      

r = 0.1224 = 12.24%

Jimmer's real income will change by 12.24% next year.                                                                                                                                                

                                                                                                                                                                                                                                                                                       

Explanation:

In the determination of the rate of change in real income, there is need          to apply Fisher's equation. The nominal rate and inflation rate have been given, thus, we will make the real rate the subject of the formula.
