Answer:
The US income will be $12,201 and South Korea's income will be $21,911. US income will grow by multiple of 1.2 while South Korea's GDP will grow by multiples of 2.19.
Step-by-step explanation:
Initial income of both the countries is $10,000.
Growth rate of South Korea is 4%.
Growth rate of US is 1%.
In 20 years, South Korea's income will be,
=Initial income*
![(1+growth rate)^(n)](https://img.qammunity.org/2020/formulas/business/high-school/ub00hmoqct9eql0fe9hqm73mc90h9umif5.png)
=$10,000*
![(1+0.04)^(20)](https://img.qammunity.org/2020/formulas/business/high-school/ddjd12jf4yzfnz22g9l16gi0blklgstln1.png)
=$10,000*2.1911
=$21,911
Similarly, we can find US income.
=Initial income*
![(1+growth rate)^(n)](https://img.qammunity.org/2020/formulas/business/high-school/ub00hmoqct9eql0fe9hqm73mc90h9umif5.png)
=$10,000*
![(1+0.01)^(20)](https://img.qammunity.org/2020/formulas/business/high-school/dg6gjnc6qgpicqjcw5bthtizxz039znml0.png)
=$10,000*1.2201
=$12,201
So, South Korea's income is $21,911 while US's income is $12,201.
South Korea's income grows by the multiples of 2.1911. While, US's income grows by the multiples of 1.2201
