Per capita income is the total income divided by country's population
Future value = Present value(1+ growth rate)^{n}
n = number of years
n = 1
Growth rate = 2% = 0.02
IAC per capita income after 1 year= 44000(1+0.02)
= 44880
DVC per capita income after 1 year = 2200(1+0.02)
= 2244
Per capita income gap between two countries = 44880 - 2244
= 42636
Correct : $42636
