Answer:
Real income has increased by $720 in terms of dollar and 2% in percentage
Explanation:
The real income is determined by adjusting the nominal income for inflation. The consumer price index (CPI) is used to measure the rate of inflation.
Real income = Nominal income × CPI Base year/ CPI in current year
Real Income =     32000 × 120/125
                =$30,720
Change Real income
Change in real income ($) = 30,720 - 30,000
                    = $ 720 Â
Change in real income (%)  =  (720/30,000) × 100
                   = 2%
Real income has increased by $720 in terms of dollar and 2% in percentage
